# Carrier wave frequency spectrum

1. The problem statement, all variables and given/known data

3. The attempt at a solution

The carrier wave is by inspection $$0.5 + cos(10\pi*t)$$ and the other would be $$1.5*sin(60\pi*t)$$.

I'm not entirely sure what we're supposed to graph for the second part, the frequency spectrum. Any help?
