    inverse Sin Cos Tan

    Is there functionality in the C or C++ library for inverse Sin, Cos, and Tan. I did skim through the C reference site but couldn't find anything, if not is there a workaround?

    You can use std::asin, std::acos and std::atan respectively. Like std::sin, std::cos and std::tan they are available via <cmath>.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    or math.h for the C versions
