# How do you find the period of 5sin2x?

May 6, 2016

$\pi$

#### Explanation:

General form of sin function is $A \sin \left(B x\right)$

Normally, the period of sin when $B = 1$ is $2 \pi$

In general, the period is $\frac{1}{B} \cdot 2 \pi$

In this case, $B = 2$ so the period is $\frac{1}{2} \cdot 2 \pi$

$= \pi$
