(d^2)/(dx^2)(2/(1+x^2))

Lösung

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

Lösung

- \frac{4 ( - 3 x ^{2} + 1 )}{( 1 + x ^{2} ) ^{3}}

Schritte zur Lösung

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

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

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

\frac{d}{d x} (- \frac{4 x}{( 1 + x ^{2} ) ^{2}}) = - \frac{4 ( - 3 x ^{2} + 1 )}{( 1 + x ^{2} ) ^{3}}

= - \frac{4 ( - 3 x ^{2} + 1 )}{( 1 + x ^{2} ) ^{3}}
