I want to find the periodicity of the following function: $$f(x) = \sin(x/2)\cos(x/3).$$ I have calculated the periodicity of the above functions which is $\pi/6$. Is it correct? Can you please help me to solve this problem?

what is your approach ? – lab bhattacharjee Jun 22 '13 at 07:17

I know that the period of sin and cos is 2pi . So the periods of sin x/2 and cos x/3 are 4Pi and 6Pi . So the period of sin x/2 cos x/3 is 6Pi – Way to infinity Jun 22 '13 at 07:20

how have you deduced $6\pi$ from $4\pi, 6\pi$ – lab bhattacharjee Jun 22 '13 at 07:26
