Overview
Grammar | COS(number) | Returns the cosine of an angle. |
Parameter | number | The angle in radians you want the cosine of. |
Notes
The function supports only one numerical parameter and returns illegal if more than one numerical parameters are set.
To express the returned angle in radians, multiply the result by PI()/180. COS(n*2*PI()+number)=COS(number) (n is an integer and the number is from - pi to pi).
Example
| Formula | Result | Notes |
|---|---|---|
| COS(0.5) | 0.877582562 | |
| COS(30*PI()/180) | 0.866025404 |
