Lösung

erweitern

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

\frac{y ^{2} - x ^{2}}{x ^{4} + 2 y ^{2} x ^{2} + y ^{4}}

Schritte zur Lösung

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

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

= \frac{y ^{2} - x ^{2}}{x ^{4} + 2 y ^{2} x ^{2} + y ^{4}}

e x p an d x sin (y) d y + (x^{3} - 2 x^{2} cos (y) + cos (y)) d y

\frac{d}{d x} ((f (x) (x)^{2}) (x^{3} - 2 x^{2} - 6))

e x p an d d x (\frac{e ^{- \frac{2 x}{L}} w ^{3}}{6} + Cw + C)

e x p an d \frac{5 x - 2}{( 5 x + 4 ) ^{2}}

e x p an d \frac{4}{s ^{2} ( s ^{2} - 4 )}
