Can someone post some examples of using sine/cosine/tangent and other trig functions in C++, I can't seem to figure out how to get it to work.

I'm used to using trig functions in the TI calculator where it's in BASIC and mega simple, but C++ has the integer-float discrepancy and I can't figure it out (because trig functions almost always have a float outcome).

Here's a list of those functions and some more and each comes with a provided sample code.

One thing I've noticed is that most people learn trig functions in degrees, but in most programming languages they are in radians. As a result, sin(90) is giving you the sine of 90 radians, not 90 degrees. If you are thinking of x as being in degrees, you would do sin(x*pi/180.0).
