Solución

Ha introducido [src]
x*sin(|x|)*sign(x)
$$x \sin{\left(\left|{x}\right| \right)} \operatorname{sign}{\left(x \right)}$$
(x*sin(|x|))*sign(x)

Primera derivada [src]
(x*cos(|x|)*sign(x) + sin(|x|))*sign(x) + 2*x*DiracDelta(x)*sin(|x|)
$$2 x \sin{\left(\left|{x}\right| \right)} \delta\left(x\right) + \left(x \cos{\left(\left|{x}\right| \right)} \operatorname{sign}{\left(x \right)} + \sin{\left(\left|{x}\right| \right)}\right) \operatorname{sign}{\left(x \right)}$$
