derivative of

x^{3} sin (7 x)

3 x^{2} sin (7 x) + cos (7 x) \cdot 7 x^{3}

Solution steps

\frac{d}{d x} (x^{3} sin (7 x))

Apply the Product Rule:

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

f = x^{3}, g = sin (7 x)

= \frac{d}{d x} (x^{3}) sin (7 x) + \frac{d}{d x} (sin (7 x)) x^{3}

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

\frac{d}{d x} (sin (7 x)) = cos (7 x) \cdot 7

= 3 x^{2} sin (7 x) + cos (7 x) \cdot 7 x^{3}

\frac{\partial}{\partial x} (sin (7 x + y + 3 z))

\frac{d}{d x} (6 + 7 x)

e^{3 x}, 0

\frac{2 s - 3}{s ^{2} + 2}

\int \frac{7 x}{x ^{2} + 1} d x
