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

Lösung

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

Lösung

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

Schritte zur Lösung

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

Multipliziere aus

\frac{x - 1}{x ^{2} - 1} : \frac{x}{x ^{2} - 1} - \frac{1}{x ^{2} - 1}

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

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

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

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

Füge eine Konstante zur Lösung hinzu

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