💡 Solution & Explanation

Function is even with  dy f ' x tan . dx 2    Hence f(x) is not differentiable at x = , 3…..(k = ). Also    f x 2a f x   same for f’(x) Area    2a 2 0 0 2 xdy 2 a sin asin 3 a               dx dy x a sin , y a 1 cos ; a 1 cos asin d d              2 2sin cos dy sin 2 2 tan dx 1 cos 2 2cos 2           not differentiable at  =  and  = – 
