|arcsin||arcsine function (radians)|
|Syntax|| arcsin (r : real) : real|
|Description|| The arcsin function is used to find the arc sine of a value. The result is given in radians. For example, arcsin (0.5) is p / 6.|
|Example|| This program prints out the arcsine of -1 through 1 in radians.|
for i : -4 .. 4 const arg := i / 4 put "Arc sine of ", arg, " is ", arcsin (arg), " radians" end for
|See also||the arccos and arctan functions for calculating arccosine and arctangent.|
the arcsind function which finds the arc sine of a value with the result given in degrees. (2p radians are the same as 360 degrees.)
