Get started and The Big Question

This section only contains one short video which asks the public to let Khan Academy know why art is important to the learner. The remainder of the section consists of text pages.

Tate is a major museum in the United Kingdom. They have multiple locations where they cover art from the last 500 years or so. Learners weighed in that art is indispensable. Art is about communications. It delights the eye. It brightens the world around us. Older art told us stories and new art begs us to question what the artist was trying to convey. Advertisers use it to make us spend our money on products. Even for someone who isn't producing art that many will see, it still provides a form of expression and outlet to relieve stress.

So, why is art important? Comment below or within the discussion on Khan Academy here.

Bookshelf-Project

**Project: Bookshelf** is the capstone project in the objects section. In this project, users are given a program that draws a single book on a bookshelf, and adds its title and star rating. This project yields 2100 points.

Users receive the following instructions:

What are your favorite books? Make a shelf of them!

1. This program only displays one book. Make an array of books (at least two of them), and use a loop to display a row of them.
2. Add an author property to each book, and display the author below the title.
3. Add a new property to each object to store a color, using the color command, and use that to fill each book differently. (Or maybe store an image?)
4. Add a boolean property to each book (like whether you would recommend it to friends), and use a conditional inside the loop to draw something different depending on whether the boolean is true or false.
5. Now add more books, and use the loop to draw more shelves down the canvas. Think about how you can use conditionals and/or the % operator to do that.

Don't want to make a bookshelf? You could also make a shelf of videos or video games, or re-create the home screen of your smartphone.

CSS

**Cascading Style Sheets**, also known as **CSS,** is how HTML items are stylized.

## Example

For example, the image above is from the KAOS CSS page. It shows part of how the founder of this wiki, Vanilla Dazzle's username appears within the chat. Her name appears in the hex color `#D32F2F` which is a shade of red. There is also code to shadow that text in the exact same shade of red.

## Usages

There are three different ways to use CSS.

1. In a stylesheet or `<style>` tag, known as external styling. That usage is what is pictured above.
2. Inline code, like the following example:

```
<element style="parameter: value;">TextContent</element>

```

     3. Applied using JavaScript or jQuery. Here is an example using jQuery.

```
<element id="el1"></element>

```

```
<script type="text/javascript">

```

```
$("#el1").css("color", "blue");

```

```
</script>

```

Graphs of Antiderivatives

The **Graphs of antiderivatives** exercise appears under the Integral calculus Math Mission on Khan Academy. This exercise shows how basic antiderivatives are graphed in respect to their constants.

## Types of Problems

There are two types of problems in this exercise:

1. Find *and graph the general indefinite integral given:* The student is asked to find the antiderivative of the function given and then graph it.
2. *Graph the original function given the antiderivative:* The student is asked to use the antiderivative to graph the original function.

## Strategies

Knowledge of basic antiderivatives concepts is encouraged to ensure success on this exercise.

1. When the original function is increasing, the antiderivative is positive.
2. When the original function is decreasing, the antiderivative is negative.
3. If the antiderivative has an interval of a zero slope, the original function has an interval of a zero slope.

Earthquakes and Volcanoes

**Earthquakes and Volcanoes**

Over millions of years, ocean basins open and close, continents move and change shape, and mountains are pushed up and eroded away. Such dynamic processes continually reshape the surface of the Earth. The movement of rigid plates on the Earth’s surface, known as plate tectonics, is the cause of these changes. Volcanic eruptions and earthquakes are dramatic hints of the great movements that take place over the vastness of geological time. American Museum of Natural History has brought you some materials to learn more about these processes.

Bronze statue of Eros sleeping

Met curator Seán Hemingway on the purity of love in Bronze statue of Eros sleeping from Greece’s Hellenistic Period, 3rd–2nd century B.C.E. The Hellenistic period introduced the accurate characterization of age. Young children enjoyed great favor, whether in mythological form, as baby Herakles or Eros, or in genre scenes, playing with each other or with pets. This Eros, god of love, has been brought down to earth and disarmed, a conception considerably different from that of the powerful, often cruel, and capricious being so often addressed in Archaic poetry. One of the few bronze statues to have survived from antiquity, this figure of a plump baby in relaxed pose conveys a sense of the immediacy and naturalistic detail that the medium of bronze made possible. He is clearly based on firsthand observation. The support on which the god rests is a modern addition, but the work originally would have had a separate base, most likely of stone.

This statue is the finest example of its kind. Judging from the large number of extant replicas, the type was popular in Hellenistic and, especially, Roman times. In the Roman period, Sleeping Eros statues decorated villa gardens and fountains. Their function in the Hellenistic period is less clear. They may have been used as dedications within a sanctuary of Aphrodite or possibly may have been erected in a public park or private, even royal, garden.

Derivatives of inverse functions

The **Derivatives of inverse functions** exercise appears within Khan Academy's Differential Calculus Math Mission. This exercise strengthens understanding of how to take the derivative of inverse functions, special derivatives, and the product rule.

## Types of Problems

There are three types of problems in this exercise:

1. *Inverse sine:* Being able to find the inverse sine and applying the product rule on the operation.

2. *Inverse cosine:* Being able to find the inverse cosine and applying the product rule on the operation.

3. *Inverse tangent:* Being able to find the inverse tangent and applying the product rule on the operation.

## Strategies

Knowledge of the inverse functions and understanding of the product rule would help to ensure successful completion of this exercise.

1. *Inverse Sine:* y = sin^-1(x)

dy/dx = 1/(sqrt(1-x^2))

2. *Inverse Cosine:* y = cos^-1(x)

dy/dx = (-1)/(sqrt(1-x^2))

3. *Inverse Tangent:* y = tan^-1(x)

dy/dx = 1/(1+x^2)

4. *Product Rule on two functions:* d/dx [f(x)g(x)] = f'(x)g(x) + f(x)g'(x)

5. *Product Rule on three functions:* d/dx [f(x)g(x)h(x)] = f'(x)g(x)h(x) + f(x)g'(x)h(x) + f(x)g(x)h'(x)

## Real-life Applications

1. Finding the tangent line of an inverse function

2. Understanding the rules of Differential calculus

Meteorite badges

According to Khan Academy, **Meteorite badges** are common and easy to earn when just getting started.

## Meteorite Badges on Khan

Meteorite Badges igenerally are the easiest to attain. The "Makes Perfect" badge, which comes from practicing one math skill, may well be the first badge many users earn. Another possible first badge is "Nice Listener," which a user earns after watching 15 minutes of video on one topic. For many topics, if a user watches all of the videos, they will surely earn this badge. Also "Apprentice Programmer". A retired Meteorite Badge that was once almost every user's first was the "Math Pretest" badge.

On the flip side, it can be debated as to which Meteorite Badge is the hardest to obtain. Some would say the "Brain Builder" badge, since the test it results from was glitching for a while, so that users couldn't access it. "Persistence" is another Meteorite Badge that some users find difficult to earn.

JavaScript

**Not to be confused with Processing JavaScript.**

**JavaScript**, commonly known as **JS**, is a programming language. It has many qualities for design based coding. It is not really focused on databases like other languages, such as SQL or the skeleton of a website, such as HTML. It has a library called PJS (Processing JavaScript), although it's hard to create an environment that accepts PJS.

Big History Project

This a longer series about "Big History" and is located in the partner content. It tells the origin stories, and then keeps going with history from a perspective that can best be described as the opposite of microscopic. It seeks to stimulate the wonder and excitement that users get from looking at the big picture. That's something often lost in the details of dates and names students learn the way history is taught today. Big History is a framework for everything. The online course draws from the crash course guys as well as new videos. The crash course videos are longer (10 to 13 minutes roughly). The videos created by the Big History project are shorter, but not short - over 2 minutes to under 10 minutes. There are quizzes, but only the first one is a good candidate for speed badges. The other ones have questions like "put several pieces in order" which slow students down when answering.

The course is meant for high school students. The course is also plenty appropriate for college students and beyond who might find it interesting. A precocious late elementary school student could even sink their teeth into this.

1. What is Big History?
2. The Big Bang
3. Stars & Elements
4. Our Solar System & Earth

Integration by Parts

The **Integration by parts** exercise appears under the Integral calculus math mission on Khan Academy. This exercise shows how to take the product of integrals using the inverse product rule.

## Types of Problems

There are three types of problems in this exercise:

1. *Evaluate the Indefinite value:* The student is asked to find the equation for the values of the integral using the inverse product rule.

2. *Evaluate the definite integral:* The student is asked to find the value of the integral by using the inverse product rule.

3. *Find the formula of the integral that will lower power on x:* The student is asked to find the formula of the integral by substituting the values and using the inverse product rule.

## Strategies

Knowledge of derivatives, antiderivatives, and the inverse product rule are encouraged to ensure success on this exercise.

1. The inverse product rule states:

∫
f
(
x
)

g
′

(
x
)
d
x

{\displaystyle \int f(x)g'(x)dx}

 =

f
(
x
)
g
(
x
)
−
∫

f
′

(
x
)
g
(
x
)
d
x

{\displaystyle f(x)g(x)-\int f'(x)g(x)dx}

∫
u
d
v

{\displaystyle \int u dv}

 =

u
v
−
∫
v
d
u

{\displaystyle uv - \int v du}

2. When solving natural logarithm, you can make the function into two functions by putting the number one outside the parenthesis.

Example:

∫
l
n
(
x
)
d
x

{\displaystyle \int ln(x) dx}

 =

∫
l
n
(
x
)
1
d
x

{\displaystyle \int ln(x)1 dx}

3. When writing the formula for the product rule, it is helpful to write the values of the of the derivatives and integrals of each function first.

4. All of the questions are multiple choice, so elimination can be used to find the correct answer.

5. The derivative and integral of

e
x

{\displaystyle e^x}

 is

e
x

{\displaystyle e^x}

(excluding the constant)

6. If the integral of the inverse product rule doesn't have a value, you can value out the equation.

Example:

2
∫
(

e
x

)
(
c
o
s
x
)
d
x

{\displaystyle 2 \int(e^x)(cosx) dx}

 =

e
x

s
i
n
x

e
x

c
o
s
x

{\displaystyle e^xsinx+e^xcosx}

∫
(

e
x

)
(
c
o
s
x
)

{\displaystyle \int(e^x)(cosx)}

 =

e
x

s
i
n
x

e
x

c
o
s
x

2

{\displaystyle {\frac{e^xsinx+e^xcosx}{2}}}

Marble Statue of Kouros

Met curator Joan R. Mertens on self-reliance in Marble Statue of a kouros (youth), c. 590–580 B.C.E. from the Attic culture of ancient Greece.

This kouros is one of the earliest marble statues of a human figure carved in Attica. The rigid stance, with the left leg forward and arms at the side, was derived from Egyptian art. The pose provided a clear, simple formula that was used by Greek sculptors throughout the sixth century B.C.E. In this early figure, geometric, almost abstract forms predominate, and anatomical details are rendered in beautiful analogous patterns. The statue marked the grave of a young Athenian aristocrat.
