x2=mod(x)2
so y=mod(x) so it is differentiable except at x=0.
Set of all points where 3√x2{x}
is differentiable?
Plz post the solution..
if you observe the function, it is the same as
3√|x|3 = |x|
so now you know?
everywhere except at x=0
its non diffrentiable at all integral point and 0
differentiable everywhere else
now the integer points are a point of concern...
the other points will be differentiable...
