Lösung

erweitern

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

\frac{- x ^{2} + 1}{x ^{4} + 2 x ^{2} + 1}

Schritte zur Lösung

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

(x^{2} + 1)^{2} = x^{4} + 2 x^{2} + 1

= \frac{- x ^{2} + 1}{x ^{4} + 2 x ^{2} + 1}

e x p an d (3 sin (y) - 5 x) d x + 2 x^{2} cot (y) d y

e x p an d \frac{x ^{2} + 2 x}{( x + 1 ) ^{2}}

e x p an d (2 + 43) (6 - 52)

e x p an d (1 + sec (x))^{2}

e x p an d \frac{e ^{x} ( 1 + x ^{2} ) - 2 x e ^{x}}{( 1 + x ^{2} ) ^{2}}
