Question20. Use the graph of $y=4 \cos (3 x)$ to solve each trigonometric equation. a) $4 \cos (3 x)-4,0 \leq x \leq 2 \pi$ b) $4 \cos (3 x)=2$ , general solution in radians

Studdy Solution
a) $x = \frac{\pi}{3}, \pi, \frac{5\pi}{3}$ b) $x = \frac{\pi}{6} + \frac{2\pi}{3}n$ and $x = \frac{5\pi}{6} + \frac{2\pi}{3}n$ , where $n$ is any integer.
