iOS Help with inverse sin in xcode

[zerocool5878]

Hello,

I know that I can do

x = sin(y)

but I need to do

x = sin-1(y)

the above doesn't seem to work.

Is there a trick to it?

Here I think this site will help. - http://www.techotopia.com/index.php/Objective-C_2.0_Operator_Precedence

What your looking for is Overriding Operator Precedence.

You're looking for the asin() function.

All math functions are documented in the math manual page. From the command line you can enter "man math" or from within Xcode choose Help -> Developer Documentation, press the "man..." button and enter "math". This will give you the math man page.
