Interesting. Compiling with the argument -lm fixed my problem. That
leads me to another question: why are the functions found in math.h in a
separate library? I would have thought that all functions found in the
standard C library would be in glibc (The K&R book I'm reading said that
math.h is a part of the standard library.)
