integral of x/(x^2-4)+x/((x^2-4)^3)

Lösung

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

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

Schritte zur Lösung

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

\int \frac{x}{x ^{2} - 4} d x = \frac{1}{2} ln x^{2} - 4

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

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