integral of ((1-x)^2)/(1+x^2)

Lösung

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

Lösung

x - ln x^{2} + 1 + C

Schritte zur Lösung

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

Lange Division

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

= \int 1 - \frac{2 x}{x ^{2} + 1} d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 1 d x - \int \frac{2 x}{x ^{2} + 1} d x

\int 1 d x = x

\int \frac{2 x}{x ^{2} + 1} d x = ln x^{2} + 1

= x - ln x^{2} + 1

Füge eine Konstante zur Lösung hinzu

= x - ln x^{2} + 1 + C
