derivative of

f (x) = 7 x^{4}

28 x^{3}

Solution steps

\frac{d}{d x} (7 x^{4})

Take the constant out:

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

= 7 \frac{d}{d x} (x^{4})

Apply the Power Rule:

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

= 7 \cdot 4 x^{4 - 1}

Simplify

= 28 x^{3}

\frac{\partial}{\partial x} (\frac{4 x y}{x ^{2} + y ^{2}})

x y^{^{'}} = y + (x + 1)^{2}

\int (x^{5} + x^{3})^{11} (5 x^{4} + 3 x^{2}) d x

\frac{( s - 1 )}{s ^{2} ( s ^{2} + 2 )}

\int sec^{5} (\frac{x}{2}) d x
