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

Lösung

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

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

Wende die Quotientenregel an:

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

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

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

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

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

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

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

\int \frac{1}{12 x} d x
