# Trigonometry Has Come Back

Algebra Level 5

The sets $$A = \big\{ z : z^{18} = 1 \big\}$$ and $$B = \big\{ w : w^{48} = 1 \big\}$$ are both sets of complex roots of unity. If we define $$C = \big\{ z \cdot w : z \in A, w \in B \big\}$$, another set of complex roots of unity, find the amount of elements in $$C$$.
