Lösung

erweitern

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

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

Schritte zur Lösung

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

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

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

e x p an d 1 + \frac{( e ^{x} - e ^{- x} ) ^{2}}{4}

\frac{d}{d y} ((x) (x - y))

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

e x p an d - \frac{40 ( - 3 x ^{2} - 4 )}{( x ^{2} - 4 ) ^{3}}

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