integral of (-2/(sqrt(11-11x^2)))

Lösung

\int (- \frac{2}{11 - 11 x ^{2}}) d x

- 2 (\frac{x}{11 - 11 x ^{2}} - \frac{1}{11} (- arcsin (x) + \frac{x}{1 - x ^{2}})) + C

Schritte zur Lösung

\int - \frac{2}{11 - 11 x ^{2}} d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - 2 \cdot \int \frac{1}{11 - 11 x ^{2}} d x

Wende die partielle Integration an

= - 2 (\frac{x}{11 - 11 x ^{2}} - \int \frac{11 x ^{2}}{( 11 - 11 x ^{2} ) ^{\frac{3}{2}}} d x)

\int \frac{11 x ^{2}}{( 11 - 11 x ^{2} ) ^{\frac{3}{2}}} d x = \frac{1}{11} (- arcsin (x) + \frac{x}{1 - x ^{2}})

= - 2 (\frac{x}{11 - 11 x ^{2}} - \frac{1}{11} (- arcsin (x) + \frac{x}{1 - x ^{2}}))
