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

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

\frac{- x ^{2} + y ^{2} + 1}{( ( x - 1 ) ^{2} + y ^{2} ) ^{2}}

Solution steps

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

Treat

y

as a constant

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

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

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

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

Simplify

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

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

\int_{5}^{53} 100 - x^{2} d x

\int e^{\frac{1}{2}}

cos^{2} (x) - sin^{2} (x)

y^{^{'}} + \frac{3 y}{x} = \frac{2}{x}

\int_{0}^{π} 15 sin^{2} (2 x) d x
