Solución

Ha introducido [src]
|x|*sin(x)
$$\sin{\left(x \right)} \left|{x}\right|$$
|x|*sin(x)
Primera derivada [src]
|x|*cos(x) + sign(x)*sin(x)
$$\sin{\left(x \right)} \operatorname{sign}{\left(x \right)} + \cos{\left(x \right)} \left|{x}\right|$$
Segunda derivada [src]
-|x|*sin(x) + 2*DiracDelta(x)*sin(x) + 2*cos(x)*sign(x)
$$- \sin{\left(x \right)} \left|{x}\right| + 2 \sin{\left(x \right)} \delta\left(x\right) + 2 \cos{\left(x \right)} \operatorname{sign}{\left(x \right)}$$
Tercera derivada [src]
-|x|*cos(x) - 3*sign(x)*sin(x) + 2*DiracDelta(x, 1)*sin(x) + 6*DiracDelta(x)*cos(x)
$$2 \sin{\left(x \right)} \delta^{\left( 1 \right)}\left( x \right) - 3 \sin{\left(x \right)} \operatorname{sign}{\left(x \right)} - \cos{\left(x \right)} \left|{x}\right| + 6 \cos{\left(x \right)} \delta\left(x\right)$$
