derivative of

f (x) = 7 x^{3}

21 x^{2}

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= 7 \cdot 3 x^{3 - 1}

Simplify

= 21 x^{2}

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

\int sin^{2} (6 x) cos^{2} (6 x) d x

x^{2}, 12 - x

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

x \to 0 lim (+ (x^{x}))
