## 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
