Vortex Sound Research

Hey guys, I'm an electrical engineering student. We have a C programming class, and we will be doing an assignment to create vocal notes using C, nothing fancy just plain old sine wave.

The purpose of this class is to be more comfortable with C syntax, memory management, io... But I'm already cool eith C with few years of programming experience. So i want to prove this and blow my teacher's mind with some fancy sounds generation.

What would you recommend as resources (book, video, course...) to learn some of the intermediate required math.
