Question

Найти производную функции в точке ноль, если: f(x)=

Answer 1

$f'(0)= \lim_{x\to 0} \frac{\sin(x\sin(3/x))}{x} = \lim_{x\to 0}\sin(3/x)=\sin(\infty)$

то есть не существует.

Answer 2

I'm sorry, but your question appears to be incomplete. Please provide the full equation for the function f(x) so I can assist you with finding its derivative at the point x=0.
