Classical Mechanics Level 4

A simple pendulum is pulled back to some angle $\theta_{max}$ and released so it swings back and forth. The angle the pendulum makes with the vertical is given by $\theta(t)$ . The maximum value $\theta_{max}$ of $\theta(t)$ is small, so you may treat the pendulum as a simple harmonic oscillator. For what fraction of time is $|\theta(t)|>\theta_{max}/3$ as the pendulum swings back and forth many times?
