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. - 10-20-2005Erondial
Yeah, I converted for degrees.

Okay. That explains ALOT.

Now, my next question is:

How would I preform a sin-1 operation? - 10-20-2005hk_mp5kpdw
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. - 10-20-2005Erondial
Thanks! I've been really bashing my head into the wall over this one. REALLY appreciate your help.
