In this question if we simplify the term we get f(x)=root 2. cosx


then here we have to take the period of cosx as 2pi  or pi( if we take Mod(cosx)


Why we have to take mod(cosx) as f(x), why not only cosx?
We should care for our environment, It is the time to save all the natural resources which we r using in our daily life. WE HAVE TO SAVE OUR PLANET EARTH.
