ASin

A command for Oblivion Script Extender

Syntax:

asin [float]

Returns the arcsine of a number (i.e. the angle whose sine this is)

Example

set theta to asin ( r / y )

Notes

• From v0005, all OBSE trigonometric functions take and return degrees. Versions of the functions which accept radians are still available by prefixing the function name with an r. (i.e. rasin)
• This function can be used in a mathematical formula (a + sin b), but a mathematical formula will not compile as the arguement for this function (sin (a + b) doesn't work).
• sin a + b = ( sin a ) + b
