# Trigonometry/Circles and Triangles/Napoleon's theorem

Napoleon's theorem (so called because some people have attributed it to Napoleon Bonaparte) states that if any triangle is taken, and an equilateral triangle constructed on each side, pointing outwards, the centroids of these three triangles are the vertices of an equilateral triangle.
The theorem is easily proved by calculating the separations of the centroids and showing that they are equal.
# Trigonometry/Circles and Triangles/Menelaus' theorem

Menelaus' theorem is due to the Greek philosopher Menelaus of Alexandria.
[Add diagram]
Let ABC be any triangle. Let a straight line cross BC at D, AC at E and AB at F (extending one side as necessary). Then
    $\displaystyle {\frac {BD}{DC}}{\frac {CE}{EA}}{\frac {AF}{FB}}=-1$.
The product is negative because one side has to be produced and so one of the segments must be treated as of negative length.
Conversely, if three points on the three sides of a triangle satisfy the above relationship, they must be collinear.
# Trigonometry/Calculating Pi

Various formulae for calculating pi can be obtained from the power series expansion for $\arctan(x)$ .
Since $\arctan(1)={\frac {\pi }{4}}$ , we have
    ${\frac {\pi }{4}}=1-{\frac {1}{3}}+{\frac {1}{5}}-{\frac {1}{7}}+{\frac {1}{9}}+\cdots$
This formula (due to Gottfried Leibniz) converges too slowly to be of practical use. However, similar formulae with much faster convergence can be found. John Machin (1680-1752) showed that
    ${\frac {\pi }{4}}=4\arctan \left({\tfrac {1}{5}}\right)-\arctan \left({\tfrac {1}{239}}\right)$ .
This formula was widely used by hand calculators. The first part of the right hand side is easy to calculate since finding ${\frac {1}{5^{n}}}$ involves very simple division, and the second part only needs 50 terms to compute 240 decimal places.
Leonhard Euler (1707-1783) showed that
    ${\frac {\pi }{4}}=5\arctan \left({\tfrac {1}{7}}\right)+2\arctan \left({\tfrac {3}{79}}\right)$ .
Störmer showed that
    ${\frac {\pi }{4}}=6\arctan \left({\tfrac {1}{8}}\right)+2\arctan \left({\tfrac {1}{57}}\right)+\arctan \left({\tfrac {1}{239}}\right)$ ,
and this formula was used in 1962 to calculate $\pi$ to over 100,000 decimals.
# Trigonometry/Circles and Triangles/Morley's Triangle

Morley's triangle was discovered by Frank Morley in 1899.
Take any triangle and trisect its three angles. These trisectors define a smaller triangle inside the first one, known as the Morley's triangle of that triangle. It is always equilateral.

### Drinking Water State Revolving Fund

"The DWSRF was established by the 1996 Safe Drinking Water Act (SDWA) Amendments to provide (low or no-interest) loans to publicly and privately owned public water systems for infrastructure improvements needed to protect public health and ensure compliance with the SDWA. As of June 30, 2002, the DWSRF had provided 2,500 loans for $5.1 billion to water systems for eligible projects." Eligible projects include:
* enhancing water system management and performance
* preventing contamination problems
* source water protection
* water efficiency activities and programs

### Clean Water State Revolving Fund

The CWSRF program was established under the U.S. Clean Water Act (CWA) of 1987 to provide loans for point source (§212), nonpoint source (§319), and estuary (§320) projects. As of June 30, 2002, the CWSRF program had privided 12,500 loans for $42.4 billion for water quality protection projects. The CWSRF funds approximately $3 to $4 billion in water quality projects each year. Water efficiency and reuse activities and projects may be considered point sources if they are developed as a component of a (publicly owned) wastewater treatment works (§212 project)."

### Restoration Credits

Under the U.S. Clean Water Act provisions for wetlands protection (section 404), owners of proposed projects which will cause unavoidable wetlands damage must provide for mitigation of that damage as a condition for receiving a 404b permit issued by the U.S. Army Corps of Engineers. One mitigation method is for the project owner to restore sufficient ecological function to compensate for the unavoidable damage to be caused by his proposed project. Or the project owner may buy "ecological credits" from someone else who has already restored ecological function, such as by removing an existing dam, as described in news article about removal of the Lowell Dam on Little River in North Carolina.

# The Legend of Zelda: Oracle of Ages/Secrets to and from Holodrum

This page lists all events that happen in Labrynna after you defeat Veran.
That is, in a linked game if you played Oracle of Ages first, then Oracle of Seasons, there is still something to do in Oracle of Ages.

## Secret to Holodrum

After clearing Oracle of Ages, you will be given the Secret to Holodrum. This is a password that can be used in Oracle of seasons when starting a new game. The new Oracle of Seasons game is known as "linked game".
Link will start the game with an extra heart and his L-1 sword. Also, ten secrets will become available, and Link can thus obtain ten extra items. Furthermore, there will be a final chapter where Link has to fight the Twinrova witches and Ganon himself.

## Ring secret

Whether you used the secret to Holodrum or not, you can also transfer all your collection of rings from one game to another. Talk to the Red Snake in Vasu's jewelry, and he'll give you a password to be told to the Red Snake in any other Oracle of Ages or Oracle of Seasons game, whether linked or not.
Since some rings are available in one game only, and some are only available in a linked game, this is the only way to get a full collection of rings.

## Ten secrets between Labrynna and Holodrum

All the secrets in this section are available only if you first cleared Oracle of Ages and then continued the game in Oracle of Seasons.
In a continued/linked game of Oracle of Seasons, ten extra characters will appear and tell a secret password for a character in Oracle of Ages. The latter characters will reply with an upgrade and a second password. Tell the password to Farore, oracle of secrets, and the upgrage will be available in Oracle of Seasons, too.
Two characters give a Magic Ring instead of an upgrade: this can be transferred using a ring secret (see#Ring secret, above) instead of talking to Farore.

### Tingle secret

* Holodrum: chapter 2, Woods of Winter
* Labrynna: Forest of Time

### Symmetry secret

* Holodrum: after dungeon 2, in Woods of Winter
* Labrynna: Symmetry City, during Ambi's age

# The Legend of Zelda: Oracle of Ages/Walkthrough

The Legend of Zelda: Oracle of Ages, like most The Legend of Zelda games, is split up primarily by the linear progression of dungeons. Typically each dungeon contains a special item that is necessary to open or get through the next dungeon, and defeating the boss of each dungeon is necessary to open up the final dungeon, the Black Tower. Note that one additional dungeon is available to players that can link up to an The Legend of Zelda: Oracle of Seasons cartridge.
This walkthrough will guide you most efficiently through the game while collecting all of the optional items. These optional parts of the game will be duly noted.
