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

21 x^{2} - 1

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

\frac{d}{d x} (7 x^{3}) = 21 x^{2}

\frac{d x}{d x} = 1

= 21 x^{2} - 1

\int_{1}^{1.5} cos (\frac{π x}{3}) d x

\frac{\partial}{\partial y} (2 e^{y} + 3 sin (y))

x^{2}, at x = 1

\frac{\partial}{\partial x} (\frac{1}{r ^{2}})

\int \frac{3}{e ^{5 x}} d x
