# How do you find the amplitude and period of #y= 4/3 sin (2/3)x#?

##### 1 Answer

This question has no sense to me, the x should be INSIDE the sinusfor being a periodic function. If the x is really out the parentesis then is a tricky question. It has no period nor amplitude..

#### Explanation:

If you really wrote it correctly then

If your equation is

for the period it is

The difference between the x's will be the period, then isolating x form
