Is it cos^3 ? Or cos(3x) ?
Period = 2pi either way

what is the period of y = 2sin(2x) + cos(3x)
~~~~~~~~~~~~~~~~~~~~~

The period for  2sin(2x)  is  2pi%2F2 = pi.


The period for   cos(3x)  is  2pi%2F3.


The period for  y = 2sin(2x) + cos(3x)  is the Least Common Multiple of  pi  and  2pi%2F3, which is  2pi.


ANSWER.  The period for  y = 2sin(2x) + cos(3x)  is  2pi.

Solved.

The answer in the post by @lynnlo is incorrect.
