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 = 
    0.7071

and the cosine of 60 degrees should be 0.5: 

--> cosd(60)

ans = 
    0.5000
