derivative of f(x)=x^3sin^2(x)

Solution

derivative of

f (x) = x^{3} sin^{2} (x)

Solution

3 x^{2} sin^{2} (x) + sin (2 x) x^{3}

Solution steps

\frac{d}{d x} (x^{3} sin^{2} (x))

Apply the Product Rule:

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

f = x^{3}, g = sin^{2} (x)

= \frac{d}{d x} (x^{3}) sin^{2} (x) + \frac{d}{d x} (sin^{2} (x)) x^{3}

\frac{d}{d x} (x^{3}) = 3 x^{2}

\frac{d}{d x} (sin^{2} (x)) = sin (2 x)

= 3 x^{2} sin^{2} (x) + sin (2 x) x^{3}
