COSD Cosine Degrees Function

Section: Mathematical Functions

Usage

Computes the cosine of the argument, but takes the argument in degrees instead of radians (as is the case for cos). The syntax for its use is
   y = cosd(x)

Examples

The cosine of 45 degrees should be sqrt(2)/2
--> cosd(45)
ans = 
  <double>  - size: [1 1]
 0.7071067811865476  

and the cosine of 60 degrees should be 0.5:

--> cosd(60)
ans = 
  <double>  - size: [1 1]
 0.5000000000000001
