    sinh

    Before I ask a long stupid question, let's start with a short one first.

    Is sinh the same function as sin-1 (as on a calculator)?

    I get the impression that it is, but if so, then it's not quite working right for me...

    No, one is the arcsine the other is the hyperbolic sine.

    Remember, the computer assumes radians, typically the calculator assumes degrees.

    Yeah, I converted for degrees.

    Okay. That explains ALOT.

    Now, my next question is:

    How would I preform a sin-1 operation?

    In your program you would use the asin() function. It takes a double as an arugment and returns a double back to the caller. The argument given to the function must be in the range +1 to -1.
