ACOSD Inverse Cosine Degrees Function

Section: Mathematical Functions


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)


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
