I'm trying to do some simple trig, and I am #including <math.h>, but the linker keeps complaining that functions like sin and cos are undefined.

Make sure you're actually linking with the math library. For instance, due to a longstanding bug in Unix and Linux systems, you usually need to use an explicit -lm flag, at the end of the command line, when compiling/linking.
