(\partial)/(\partial x)(x^2sin(x))

\frac{\partial}{\partial x} (x^{2} sin (x))

2 x sin (x) + cos (x) x^{2}

Solution steps

\frac{\partial}{\partial x} (x^{2} sin (x))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{2}, g = sin (x)

= \frac{\partial}{\partial x} (x^{2}) sin (x) + \frac{\partial}{\partial x} (sin (x)) x^{2}

\frac{\partial}{\partial x} (x^{2}) = 2 x

\frac{\partial}{\partial x} (sin (x)) = cos (x)

= 2 x sin (x) + cos (x) x^{2}
