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(- π )= -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 -
