integral of (4/(x^5)-5/(x^2)+7/x)

Lösung

\int (\frac{4}{x ^{5}} - \frac{5}{x ^{2}} + \frac{7}{x}) d x

- \frac{1}{x ^{4}} + \frac{5}{x} + 7 ln ∣ x ∣ + C

Schritte zur Lösung

\int \frac{4}{x ^{5}} - \frac{5}{x ^{2}} + \frac{7}{x} 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{4}{x ^{5}} d x - \int \frac{5}{x ^{2}} d x + \int \frac{7}{x} d x

\int \frac{4}{x ^{5}} d x = - \frac{1}{x ^{4}}

\int \frac{5}{x ^{2}} d x = - \frac{5}{x}

\int \frac{7}{x} d x = 7 ln ∣ x ∣

= - \frac{1}{x ^{4}} - (- \frac{5}{x}) + 7 ln ∣ x ∣

Vereinfache

= - \frac{1}{x ^{4}} + \frac{5}{x} + 7 ln ∣ x ∣
