User:System86/Cos

Implements the mathematical cosine function, from an input in radians. Implemented with the #expr parser function.

For the value of pi, you can actually use "pi".

Usage:

{{Cos|radians}}

Examples:

• cos(- Ï€  ) = -1
• cos(-5Ï€/6) = -0.866025403784
• cos(-3Ï€/4) = -0.707106781187
• cos(-2Ï€/3) = -0.5
• cos(- π/2) = 6.12323399574E-17
• cos(- π/3) = 0.5
• cos(- π/4) = 0.707106781187
• cos(- π/6) = 0.866025403784
• cos(  0  ) = 1
• cos(  Ï€/6) = 0.866025403784
• cos(  Ï€/4) = 0.707106781187
• cos(  Ï€/3) = 0.5
• cos(  Ï€/2) = 6.12323399574E-17
• cos( 2Ï€/3) = -0.5
• cos( 3Ï€/4) = -0.707106781187
• cos( 5Ï€/6) = -0.866025403784
• cos(  Ï€  ) = -1
