## ACOSD Inverse Cosine Degrees Function

Section: Mathematical Functions

### Usage

Computes the inverse cosine of the argument, but returns the argument in degrees instead of radians (as is the case for `acos`. The syntax for its use is

       y = acosd(x)

### Examples

The inverse cosine of `sqrt(2)/2` should be 45 degrees:

    --> acosd(sqrt(2)/2)

    ans =
      45.0000 +  0.0000i

and the inverse cosine of `0.5` should be 60 degrees:

    --> acosd(0.5)

    ans =
      60.0000 +  0.0000i
