| 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
