derivative of

\frac{x + 6}{x ^{3} + x - 7}

\frac{- 2 x ^{3} - 18 x ^{2} - 13}{( x ^{3} + x - 7 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x + 6}{x ^{3} + x - 7})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d x} ( x + 6 ) ( x ^{3} + x - 7 ) - \frac{d}{d x} ( x ^{3} + x - 7 ) ( x + 6 )}{( x ^{3} + x - 7 ) ^{2}}

\frac{d}{d x} (x + 6) = 1

\frac{d}{d x} (x^{3} + x - 7) = 3 x^{2} + 1

= \frac{1 \cdot ( x ^{3} + x - 7 ) - ( 3 x ^{2} + 1 ) ( x + 6 )}{( x ^{3} + x - 7 ) ^{2}}

Simplify

\frac{1 \cdot ( x ^{3} + x - 7 ) - ( 3 x ^{2} + 1 ) ( x + 6 )}{( x ^{3} + x - 7 ) ^{2}} : \frac{- 2 x ^{3} - 18 x ^{2} - 13}{( x ^{3} + x - 7 ) ^{2}}

= \frac{- 2 x ^{3} - 18 x ^{2} - 13}{( x ^{3} + x - 7 ) ^{2}}

\int x (x + 4)^{6} d x

\int_{0}^{1} cos^{2} (x) d x

\frac{d}{d x} (ln (6 x + 1))

\frac{\partial}{\partial x} (yz - ln (x + z))

f (x) = x^{2} 2 x + 4
