Answer 2

$\huge \boxed { \blue{\bold{Answer}}}$

f(x)=∣sinx∣

Since sinx is a continuous function ∣sinx∣is also a continuous function over R

f′(x)=sinx∣sinx∣×cosx(dxd∣x∣=x∣x∣)

x→nπ+limsinx∣sinx∣×cosx=x→nπ+limsinxsinx×cosx

=−x→nπ+limcosx

x→nπ−limsinx∣sinx∣×cosx=x→nπ−limsinxsinx×cosx

=x→nπ−limcosx

Since Right limit is not equal to left limit 

Limit at nπ does not exist (where n is any integer).
