(\partial)/(\partial x)(x/((x-1)^2))

\frac{\partial}{\partial x} (\frac{x}{( x - 1 ) ^{2}})

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

Solution steps

\frac{\partial}{\partial x} (\frac{x}{( x - 1 ) ^{2}})

Apply the Quotient Rule:

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

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

\frac{\partial}{\partial x} (x) = 1

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

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

Simplify

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

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

\int x \cdot 1 + \frac{1}{4 x} d x

y^{^{'''}} + y^{^{''}} = 8 x^{2}

\int 2 sin^{2} (x) cos^{3} (x) d x

\int \frac{1}{a ^{2} - u ^{2}} d u

\int_{0}^{x} sin (\frac{π t ^{2}}{2}) d t
