Description

Returns the inverse sine of x, in that if dsin(x)=n, darcsin(n)=x, and the resulting number will be between -90 and 90.

NOTE:This will only accept a number between -1 and 1 (anything else will throw an error).

Syntax:

darcsin(x);

Returns:

Real

Example:

val = darcsin(-1);

This will set "val" to -90.
