What is the period T of the function y=3sin(4x)?

## Answer

y=3sin(4x) sompare withy= A sin wx w= 4

or, 2pi/T=4

**T= pi/2 s**

=1.57 s

=1.57 s

We know that the period of y=sinx is pi So period of y=sin(4x) is pi/4 Period of y=3sin(4x) is (pi/4)/3 =pi/12

So T=pi/12

a period is when one cycle is completed.

So, if you set y=0 and solve the the x-values.

The different between two immediate x-values is the period.
