## On the Subject of Forget The Colors

Since when was trigonometry relevant to colors?

This module has 2 displays, a gear LED and number, 2 nixies, 3 cylinders, and a key. Note them down at the start, and after each solve. Colorblind mode uses ‘I’ as Pink and ‘P’ as Purple. If the background is green, refer to Forget Any Color.

#### For every stage on the module:

- Use the table to modify each nixie with their respective ‘L’/‘R’ columns from every cylinder left to right. Don’t record decimals and ignore divisions (/) or modulo (%) 0. Modulo both nixies by 10.
- Within the table, start on the color of the LED on the gear. Move up
**left nixie**and move down**right nixie**, wrapping if needed. - Create a 3-digit number with the left- then right nixie, and then the current ‘Edgework’ color plus both nixies plus the gear number modulo 10.
Get the Sine (sin) of that 3-digit number and take the first five digits of the sine past the decimal point. This number can be negative. Write this 3-digit number to get the first 5 decimals in sine.

Take the 3-digit display and get the first five digits of Cosine (cos) past the decimal point. Drop any negative signs to maintain a positive value. Write the 3-digit display to get the first 5 decimals in absolute cosine.

- Get the sum of sine and cosine.
**This number is needed later.**

Color | L | R | Edgework |
---|---|---|---|

Red | +5 | -1 | + batteries |

Orange | -1 | -6 | - ports |

Yellow | +3 | +0 | + serial’s last digit |

Green | +7 | -4 | - solved modules |

Cyan | -7 | -5 | + port plates |

Blue | +8 | +9 | - modules |

Purple | +5 | -9 | + battery holders |

Pink | -9 | +4 | - lit indicators |

Maroon | +0 | +7 | + indicators |

White | -3 | +5 | - unlit indicators |

#### When cylinders turn gray:

Add up all of the stage numbers, taking only the decimals.

Take this value and apply a cos^{-1} to it. This will require at least a scientific calculator. Floor the given value and drop all of the decimal values to get a number from 0 and 90.
Keep it positive and use floored cos^{-1} below.

Input the number in the 2 nixies, then turn the key. When struck, cycle stages with the nixies. Turn the key to retry. Submit 90 if there were 0 stages.
