~~~~~~~~~~~~~~~~~~~~~


<pre>
The period for  2sin(2x)  is  {{{2pi/2}}} = {{{pi}}}.


The period for   cos(3x)  is  {{{2pi/3}}}.


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


<U>ANSWER</U>.  The period for  y = 2sin(2x) + cos(3x)  is  {{{2pi}}}.
</pre>

Solved.
