Question

which of the function is not differentiable?

Answer 1

The correct answer I'd d
HOPE THIS HELPS YOU

Answer 2

answer is option (C)

f(x) = cotx

is not differentiable in ( -π/2 , π/2]

reason:→

f(x) = Cotx
= cosx/sinx

but given domain of function f(x)
is take infinite value at x =0

so function is not differentiable at x =0

then we can say that function is not differentiable in given domain .
