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

- \frac{3 a}{x ^{4}}

Solution steps

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

Take the constant out:

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

= a \frac{d}{d x} (\frac{1}{x ^{3}})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

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

Apply the Power Rule:

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

= a (- 3 x^{- 3 - 1})

Simplify

a (- 3 x^{- 3 - 1}) : - \frac{3 a}{x ^{4}}

= - \frac{3 a}{x ^{4}}

\int \frac{1}{cos ^{2} ( u )} d u

\frac{\partial}{\partial z} (y)

\frac{d}{d x} (e^{c o s h (3 x)})

\int \frac{1}{4 - 3 sin ^{2} ( x ) + 5 cos ^{2} ( x )} d x

\int \frac{1 - cos ( 2 θ )}{2} d θ
