Derivada de x*sin(|x|)*sign(x)
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|)
$$2 x \sin{\left(\left|{x}\right| \right)} \delta\left(x\right) + \left(x \cos{\left(\left|{x}\right| \right)} \operatorname{sign}{\left(x \right)} + \sin{\left(\left|{x}\right| \right)}\right) \operatorname{sign}{\left(x \right)}$$
Segunda derivada
[src]
/ / 2 \ \ - \x*\sign (x)*sin(|x|) - 2*DiracDelta(x)*cos(|x|)/ - 2*cos(|x|)*sign(x)/*sign(x) + 4*(x*cos(|x|)*sign(x) + sin(|x|))*DiracDelta(x) + 2*x*DiracDelta(x, 1)*sin(|x|)
$$2 x \sin{\left(\left|{x}\right| \right)} \delta^{\left( 1 \right)}\left( x \right) - \left(x \left(\sin{\left(\left|{x}\right| \right)} \operatorname{sign}^{2}{\left(x \right)} - 2 \cos{\left(\left|{x}\right| \right)} \delta\left(x\right)\right) - 2 \cos{\left(\left|{x}\right| \right)} \operatorname{sign}{\left(x \right)}\right) \operatorname{sign}{\left(x \right)} + 4 \left(x \cos{\left(\left|{x}\right| \right)} \operatorname{sign}{\left(x \right)} + \sin{\left(\left|{x}\right| \right)}\right) \delta\left(x\right)$$
Tercera derivada
[src]
/ / 3 \ 2 \ / / 2 \ \ - \x*\sign (x)*cos(|x|) - 2*DiracDelta(x, 1)*cos(|x|) + 6*DiracDelta(x)*sign(x)*sin(|x|)/ - 6*DiracDelta(x)*cos(|x|) + 3*sign (x)*sin(|x|)/*sign(x) - 6*\x*\sign (x)*sin(|x|) - 2*DiracDelta(x)*cos(|x|)/ - 2*cos(|x|)*sign(x)/*DiracDelta(x) + 6*(x*cos(|x|)*sign(x) + sin(|x|))*DiracDelta(x, 1) + 2*x*DiracDelta(x, 2)*sin(|x|)
$$2 x \sin{\left(\left|{x}\right| \right)} \delta^{\left( 2 \right)}\left( x \right) - 6 \left(x \left(\sin{\left(\left|{x}\right| \right)} \operatorname{sign}^{2}{\left(x \right)} - 2 \cos{\left(\left|{x}\right| \right)} \delta\left(x\right)\right) - 2 \cos{\left(\left|{x}\right| \right)} \operatorname{sign}{\left(x \right)}\right) \delta\left(x\right) + 6 \left(x \cos{\left(\left|{x}\right| \right)} \operatorname{sign}{\left(x \right)} + \sin{\left(\left|{x}\right| \right)}\right) \delta^{\left( 1 \right)}\left( x \right) - \left(x \left(6 \sin{\left(\left|{x}\right| \right)} \delta\left(x\right) \operatorname{sign}{\left(x \right)} - 2 \cos{\left(\left|{x}\right| \right)} \delta^{\left( 1 \right)}\left( x \right) + \cos{\left(\left|{x}\right| \right)} \operatorname{sign}^{3}{\left(x \right)}\right) + 3 \sin{\left(\left|{x}\right| \right)} \operatorname{sign}^{2}{\left(x \right)} - 6 \cos{\left(\left|{x}\right| \right)} \delta\left(x\right)\right) \operatorname{sign}{\left(x \right)}$$
