|arccosd||arccosine function (degrees)|
|Syntax|| arccosd (r : real) : real|
|Description|| The arccosd function is used to find the arc cosine of an angle given in degrees. For example, arccosd (0.5) is 60.|
|Example|| This program prints out the arccosine of values from -1 to 1 in degrees.|
for i : -4 .. 4 const arg := i / 4 put "Arc cosine of ", arg, " is ", arccosd (arg), " degrees" end for
|See also||the arcsind and arctand functions for calculating arcsine and arctangent|
the arccos function which finds the arc cosine of a value with the result given in radians. (2p radians are the same as 360 degrees.)
