find the period of the sinusoidal function.\nsimplify any fractions.\nperiod =

Answer:

$2\pi$

Explanation:

Step1: Identify one - cycle

Observe the graph for one full wave.

Step2: Measure horizontal length

The horizontal length from one peak to the next peak is from $-\pi$ to $\pi$.

Step3: Calculate period

$\pi-(-\pi)=2\pi$.
