derivative of

f (x) = \frac{4 x}{( x - 1 ) ^{2}}

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

Solution steps

\frac{d}{d x} (\frac{4 x}{( x - 1 ) ^{2}})

Take the constant out:

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

= 4 \frac{d}{d x} (\frac{x}{( x - 1 ) ^{2}})

Apply the Quotient Rule:

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

= 4 \cdot \frac{\frac{d x}{d x} ( x - 1 ) ^{2} - \frac{d}{d x} ( ( x - 1 ) ^{2} ) x}{( ( x - 1 ) ^{2} ) ^{2}}

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

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

= 4 \cdot \frac{1 \cdot ( x - 1 ) ^{2} - 2 ( x - 1 ) x}{( ( x - 1 ) ^{2} ) ^{2}}

Simplify

4 \cdot \frac{1 \cdot ( x - 1 ) ^{2} - 2 ( x - 1 ) x}{( ( x - 1 ) ^{2} ) ^{2}} : \frac{4 ( - 1 - x )}{( x - 1 ) ^{3}}

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

\int (x^{3} + 7) d x

\frac{d ^{2}}{d x ^{2}} (3 csc (x))

\int_{- 2}^{2} 16 - 4 x^{2} d x

\int - \frac{ln ( x )}{x ^{2}} d x

- 72 x
