Solution


The function y=cos3(3x)y = \left| {\,{{\cos }^3}\left( {3x} \right)\,} \right| is plotted and is shown below.





As per the plot above a couple of cycles has been plotted


It is obvious that the period is p=π3p = \frac{\pi }{3}


Hence the statement "the period of the function f(x)= |cos^3 3x| is pi/3", is TRUE
