integral of (arccos(x)-x)/(sqrt(1-x^2))

Lösung

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

Lösung

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

Schritte zur Lösung

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

Multipliziere aus

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

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

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

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

= - \frac{arccos ^{2} ( x )}{2} - (- 1 - x^{2})

Vereinfache

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

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