# Real function/Indicator function not negative/Not continuous/Example

We consider the function
    $f\colon \mathbb {R} \longrightarrow \mathbb {R} ,$
given by
    $f(x)={\begin{cases}0,{\text{ if }}x<0\,,\\1,{\text{ if }}x\geq 0\,.\end{cases}}\,$
This function is not continuous in $0$. For $\epsilon ={\frac {1}{2}}$ and every positive $\delta$, there exists a negative number $x'$ such that $d(0,x')=\vert {x'}\vert \leq \delta$. But for such a number we have $d(f(0),f(x'))=d(1,0)=1\not \leq {\frac {1}{2}}$.
# Real function/Open interval/Local extrema/Differentiable/Derivative zero/Fact/Proof

We may assume that $f$ attains a local maximum in $c$. This means that there exists an $\epsilon >0$, such that $f(x)\leq f(c)$ holds for all $x\in [c-\epsilon ,c+\epsilon ]$. Let ${\left(s_{n}\right)}_{n\in \mathbb {N} }$ be a sequence with $c-\epsilon \leq s_{n}<c$, tending to $c$ ("from below“). Then $s_{n}-c<0$, and so $f(s_{n})-f(c)\leq 0$, and therefore the difference quotient
    ${\frac {f(s_{n})-f(c)}{s_{n}-c}}\geq 0\,.$
Due to fact, this relation carries over to the limit, which is the derivative. Hence, $f'(c)\geq 0$. For another sequence ${\left(t_{n}\right)}_{n\in \mathbb {N} }$ with $c+\epsilon \geq t_{n}>c$, we get
    ${\frac {f(t_{n})-f(c)}{t_{n}-c}}\leq 0\,.$
Therefore, also $f'(c)\leq 0$ and thus $f'(c)=0$.
# Real function/Identity on Q/Else 0/Continuous in 0/Exercise

Prove that the function
    $f\colon \mathbb {R} \longrightarrow \mathbb {R}$
defined by
    $f(x)={\begin{cases}x,\,{\text{ if }}x\in \mathbb {Q} \,,\\0,\,{\text{ otherwise}}\,,\end{cases}}\,$
is only at the zero point $0$ continuous.
# Real function/Open interval/Local extrema/Differentiable/Derivative zero/Fact

Let
    $f\colona,b\longrightarrow \mathbb {R}$
be a function which attains in $c\ina,b$ a local extremum, and is differentiable there.
$f'(c)=0$

# Ten stupid things beginners do to mess up their contradance experience/Tolerating Bad Behavior from Other Dancers
## 7. Tolerating Bad Behavior from Other Dancers.

This really isn't a stupid thing to do as much as it's a byproduct of being an inexperienced dancer. Sometimes (but rarely), you may run across a dancer who will be overly familiar to a greater or lesser degree. Occasionally, someone will interact with you on the dance floor in a way that is painful (because the figure is improperly done) or that makes you uncomfortable. With all the bodies on the floor whirling around each other in close proximity, some inadvertent contact that you wouldn't expect from a stranger is bound to happen, most of it clearly accidental and unintentional.
However, if you think the contact was intentional, or that another dancer has done something inappropriate, please let the dance organizers know who it was and what was done when you are done with that dance. They will know if others have complained about that dancer, and can keep an eye out to see whether this is part of a pattern of behavior, or just an isolated incident.
While it's incredibly rare, if the behavior was criminal then it may even be appropriate to involve the police to address the situation. First, of course, talk to the dance organizers, even about something that seems minor and petty. This is only mentioned for completeness; a contra dance is as safe an event as you will find, and it's virtually unheard of for this sort of behavior to happen on the dance floor. Another way to say this is that this kind of conduct is so rare that you can dance for decades without experiencing it. Most dancers never have and never will.

# Ten stupid things beginners do to mess up their contradance experience/Waiting to Be Asked
## 3. Waiting To Be Asked To Dance.

Remember middle-school dances? Your first contradance can feel a lot like being back in middle-school, either sitting around the wall waiting impatiently for someone to notice you and come over to ask you to dance, or trying to get your courage up to ask someone else to dance when you don't know anybody (this dynamic has a lot to do with Stupid Thing #4, actually). However, contradance isn't like a middle-school dance. This is social dance, and a partner is your “ticket” to the dance – you can't dance without one, but you won't be dancing only with them. Also, traditionally, you don't dance with the same partners twice in a row (some don't dance with the same partner twice in an evening), so being a partner once in the evening doesn't have that baggage of romantic interest or commitment we had in middle-school dances.
Experienced dancers will frequently look close to them when picking partners, so being on the floor (as opposed to sitting on a chair at the side of the room) will substantially improve your chances of being asked to dance. (Dancers tend to assume that those sitting on the side are resting, although some will ask sitters if the standing dancers are already all partnered up). It's also quite acceptable in the contradance communities for women to ask men to dance. If you know you want to dance with a particular partner, and you've sat out a dance, you can even move yourself toward that intended partner during the final chord and applause at the end of the dance sequence to be available for asking or just ask them.
Some experienced dancers are also afraid of asking strangers to dance, but a smile and inquiring glance with your hand up will usually be sufficient to let them know what you have in mind.

# Tensor

In mathematics, a tensor is a certain kind of geometrical entity and array concept. It generalizes the concepts of scalar, vector (geometric) and linear operator, in a way that is independent of any chosen frame of reference. For example, doing rotations over axis does not affect at all the properties of tensors, if a transformation law is followed. Tensors are of importance in pure and applied mathematics, physics and engineering.

# Tensors

          Note: This series of articles takes a radical view of the subject. Most textbooks and internet resources define a tensor as a mathematical object defined by certain parameters ("indices" or "components"), the transformation properties of which define the nature of the tensor. These articles instead define tensors as pure mathematical objects, and only derive the transformation formulas in the last article.
A tensor is a concept from mathematical physics that can be thought of as a generalization of a vector. While tensors can be defined in a purely mathematical sense, they are most useful in connection with vectors in physics.
The subject has a reputation for being difficult to learn. These articles will attempt to give a straightforward explanation in terms of the fundamental concepts, rather than the more common explanation in terms of the way the components are transformed under a change of coordinate system.

# Ten stupid things beginners do to mess up their contradance experience/Skipping the Beginners Workshop
## 2. Skipping the Beginners' Workshop.

If you've shown up at your first dance too late for the beginners' workshop (or, if this is a festival where the dance isn't preceded by a beginners' workshop), there's no way of undoing it, but plan to attend at your next opportunity. If you haven't yet gone to your first dance, plan to be there several minutes before the workshop is scheduled to start. Workshops are usually taught by the evening's caller, who will teach the most common basic figures, and give you some idea of how he or she will call those figures as the evening progresses. This basic instruction gives you a real leg up on the night – you're not nearly as much of a beginner after attending the workshop as you would be without it.
Sometimes first-time dancers skip the workshop and show up late because they've been out having a nice dinner with wine. This really sets you up for failure in several ways: you throw yourself into the deep end because you miss the workshop, you're not processing new information as well as you would cold sober, and you're trying to do vigorous exercise on a full stomach.

# Finite-dimensional vector space/Linear mapping/Two generalized eigenspaces/Fact

For a linear mapping $\varphi \colon V\rightarrow V$ on a finite-dimensional $K$-vector space $V$ and two eigenvalues $\lambda \neq \delta$,
generalized eigenspace have trivial intersection, that is
    $\operatorname {GeEig} _{\lambda }(\varphi )\cap \operatorname {GeEig} _{\delta }(\varphi )=0\,.$
# Finite-dimensional vector space/Linear mapping/Two generalized eigenspaces/Fact/Proof

The characteristic polynomial of $\varphi$ has the form
    $\chi _{\varphi }=(X-\lambda )^{k}(X-\delta )^{\ell }F\,,$
where neither $\lambda$ nor $\delta$ is a zero of $F$. Because of fact, applied to $Q=(X-\delta )^{\ell }F$, we have
    $\operatorname {GeEig} _{\lambda }(\varphi )\cap \operatorname {kern} Q(\varphi )=0\,.$
Because of $\operatorname {GeEig} _{\delta }(\varphi )\subseteq \operatorname {kern} Q(\varphi )$, this implies immediately
    $\operatorname {GeEig} _{\lambda }(\varphi )\cap \operatorname {GeEig} _{\delta }(\varphi )=0\,.$
# Aquaria/Clownfish breeding

The anemone fish, better known as the clownfish, are popular fish in the tanks of many saltwater aquarium enthusiasts. They are generally found in the warm waters of the Pacific and Indian Oceans. Clownfish live at the bottom of shallow seas in sheltered reefs or in shallow lagoons. They are also one of the first saltwater fish known to breed in captivity. Breeding fish instead of capturing them from the wild has many advantages; breeding is much more ecofriendly and sustainable, and the fish are healthier and less susceptible to diseases.

## Paired/spawning clownfish

All clownfish are born as males, but are hermaphroditic. The most dominant one in a group becomes larger than the rest and morphs into a female. The next in the chain of hierarchy becomes the breeding male. The remaining fish will remain nongendered until the breeding male or female dies. Techniques to pair clownfish are available, but the easiest way to ensure a paired set of clownfish is to purchase them as such.
* In paired clownfish, the male is the smaller of the two.
* A newly laid clutch of about 250 eggs can be seen at the top of the inside of the clay pot. They are orange in color and capsule-shaped.
* The male's primary roles are to clean and aerate the eggs and protect them from predators.

## Rotifer culture

Adult clownfish in captivity will eat a variety of foods, but clownfish fry instinctively only eat live and moving prey they can hunt. A suitable food source for clownfish fry is rotifers. Rotifers have a short lifespan of about five days, so they need to be cultured because they are usually not sold in pet stores. A start-up culture must be purchased. Many establishments culture and ship rotifers. The culture, as well as the rotifer diet, was obtained from Reed Mariculture. Keeping the rotifer culture alive can be just as, or even more, challenging than the fry. A culture must be established prior to spawning.

## Story

Tell a detailed story of the project. Describe how split up, what the obstacles were, what testing was done, what informal decisions were made, what assumptions were made, and what the results were.
* The display tank is a 93-gallon cube.

# Aquaria/Ember tetra

The ember tetra (Hyphessobrycon amandae) is a freshwater tropical fish native to the Araguaia River basin of Brazil. This species is of typical tetra shape, but grows to a maximum overall length of about 2 cm (0.7 in). Most exhibit striking orange and reddish coloration with mild translucency near their pelvic fins. Their eyes frequently mirror the color of the fish and are outlined in black. The fish's natural diet consist of small invertebrates and plants. Although somewhat hard to find in fish stores, H. amandae is commonly kept as an aquarium fish by hobbyists.

## In the aquarium

Ember tetras should be kept in acidic water with a pH near 6.6, and although their native habitat has very soft water, they have adapted quite well to a wide range of hardness (5-17 dGH). The recommended temperature range is between 23 and 29°C (73 and 84°F). Ideally, their tank should contain live plants, a darker substrate, and open water for swimming. Ember tetras should be kept in groups of at least five, to promote schooling. They appreciate a heavily planted aquarium, ideally with a small area shaded from direct light, and spend time swimming through planted areas, which also offer some protection for their fry.
Ember tetras will school with other tetras, such as the neon tetra, but may become stressed by the presence of significantly larger fish. These fish swim at the middle level of the aquarium, and do not feed from the bottom of the tank. Therefore, they should be kept with other bottom-dwelling fish (such as pygmy corydoras), so leftover food is then eaten from the substrate and not left to spoil. Ember tetras can be fed a variety of foods, including flake, frozen, and freeze-dried food. Small live foods, worms and brine shrimp, are also recommended as they bring out the fish's colors.
In a well-maintained, heavily planted aquarium, ember tetras have been known to live ten years or more.
# Aquaria/Diamond tetra

The diamond tetra, Moenkhausia pittieri, is a small freshwater tropical fish found in and around Lake Valencia in Venezuela. Males have much longer dorsal fins than the females and tend to be more brightly coloured, but both sexes are attractive fish and have become popular with aquarists. The dorsal and anal fins are purple and the body is silver. The eye is marked with red above the pupil, and a dark band runs along the midline of the body. Their common name comes from the bright, iridescent scales along the flanks. Maintenance in aquaria is similar to that of other tetras, although they will not do as well in hard, alkaline water as they do in soft, slightly acidic water filtered through peat.
The diamond tetra is an omnivore. In the wild they eat whatever they can get, with a preference for animal food, especially mosquito larvae. In an aquarium, they eat most normal fish foods, including flakes. They benefit from a variety of food such as live daphnia or frozen bloodworms.

## Breeding

A pair of diamond tetras spawns in an aquarium with an area well planted with fine-leaved plants to create a shaded area. The pair should be well conditioned before breeding with rich foods, including live food. The tank should be darkened before and during breeding, and then the light should slowly be increased over a few days to create a natural lighting.
The water should be very soft and a pH of 6 is preferable. A temperature of 28°C (79°F) is suitable. The fish usually spawn in the early morning. They will eat their eggs, so are normally removed after spawning. The eggs normally hatch in 36 hours and the fry are usually swimming free in four days. The young grow quickly; they will eat fry foods, but suitably sized live foods help at all stages.
# Aquaria/Buenos Aires tetra

The Buenos Aires tetra (Hyphessobrycon anisitsi) is a tropical fish from the Paraná and Uruguay River basins of South America. It swims in shoals.
An aquarium subject for over 60 years, the Buenos Aires tetra is a metallic-coloured fish, with red-tipped fins and a black marking on the dorsal fin. It is also a large tetra, growing to 7 cm.
The Buenos Aires tetra is an undemanding and inexpensive fish. However, it is best kept away from delicate and shy species, because it is a fin nipper. It also has a tendency to eat aquarium plants. This fish has a similar omnivorous diet to most tetras. It accepts flake and dried foods, as well as vegetable matter. This fish requires more food than most small aquarium fish. They are adapted to temperatures of 62–83°F (17–28°C). The Buenos Aires tetra will tolerate a pH of 5.5–8.5.
# Aquaria/Congo tetras

In the aquarium, mimic the natural habitat for the Congo tetra; it requires soft, peat-filtered (acidic) water and a darker substrate. They are most comfortable in an aquarium with lower light levels. The beautiful rainbow colors of this fish will also show best in lower light levels. These fish are easily frightened by aggressive tank mates and loud noises, and may wait for people to leave the aquarium area before they will feed. It is a peaceful schooling fish, so needs a large aquarium to thrive and develop its full beauty. Any aquarium less than 30 gallons will not be suitable for a proper school of these fish. Water hardness should be 4-18°dGH, pH should be near 6.2, and temperature should be 75-81°F (24-27°C)

## Nutrition

Since they are omnivorous, Congo tetras generally eat all kinds of live, fresh, and flake foods. To keep a good balance, give them a high-quality flake food every day. Feed brine shrimp (either live or frozen) or bloodworms as a treat.

## Social behavior

They are generally good community fish, but they may try to bite smaller fish. Also, they may eat smaller plants. They sometimes nibble on softer plants and young shoots.

## Breeding and reproduction

Congo tetras are egg layers. Some keys to breeding them are a large aquarium, peat-filtered water, and bright lighting to initiate spawning. They will lay up to 300 eggs that will drop to the bottom. The fry are large enough to eat freshly hatched brine shrimp.
# Aquaria/Costello tetra

The Costello tetra is a freshwater tropical fish from the Amazon basin in Brazil and Peru.
In the wild, this fish comes from soft or very soft and slightly acidic water. In an aquarium, some attempt to mimic these water conditions is necessary. A pH between 6.0 and 7.5, hardness up to 15° general hardness, and temperature of 23–27°C (73–81°F) are ideal.
The Costello tetra is an omnivore with a preference for animal foods, such as small worms, crustaceans, and insect larvae. In an aquarium they eat good-quality fish flakes readily. They benefit from a variety of foods, such as live and frozen foods, including bloodworms.
# Aquaria/Bleeding heart tetra

The bleeding heart tetra, Hyphessobrycon erythrostigma, is a peaceful midlevel-dwelling community fish in the aquarium. It grows to 64 mm long and lives about five years. It requires warm water (78°F or 26°C). This fish, like most tetras, needs soft, acid water, pH 6.5-6.8, with plenty of plants. This fish is somewhat susceptible to velvet disease and Ichthyophthirius multifiliis. It is sensitive to water conditions and requires frequent partial water changes.
Bleeding hearts are generally peaceful fish, but fin nipping may become a problem, as males can be territorial. They are best kept in a small school (six or more) and not with fish with larger fins such as angelfish and bettas. They do well in a variety of community tanks, and like most tetras, do best in groups and with bushy plants. They are a suitable tankmate for corydoras and other bottom-dwelling species. With a few exceptions they are peaceful when surrounded by their own kind, like tiger barbs. They are also mischievous, nipping at others' tails and entering their territory looking for food.
The female is more full-bodied and the male has a larger dorsal fin. The male is distinguished by longer extended dorsal and anal fins. The dorsal fin is elongated into a sickle shape that arches to the length of the tail base. The female has a shorter, rounded fin. Breeding is hard but not impossible. They have been bred in captivity and are egg layers.
This tetra has a splendid body shape and, after a month or two in captivity, the colors get very beautiful, especially when fed (two or three days a week) with frozen brine shrimp. The dorsal fin of the males can become long and flowing. Both sexes have the eye-catching, blood-red spot at the heart area. Both also have the black and white patch on the dorsal fin.
The bleeding heart tetra is readily available. It can be obtained from most fish and pet stores, as well as on line
