1.7.9 Solve simple trigonometric equations

Question 4

The intensity of polarized light, $I$ , passing through a rotating filter is modeled by the equation

I_0 \cos^2 \theta

where $I_0$ is the maximum intensity and $θ\theta$ is the angle of the filter in radians. In a specific experiment, the maximum intensity is measured as $I_0 = 12$ units. Determine all values of $θ\theta$ in the interval $\le \theta \le 2\pi$ for which the intensity $I$ is exactly $9$ units. Give your answers in terms of $π\pi$ .
