integral of 3/x-4/(x^5)

Lösung

\int \frac{3}{x} - \frac{4}{x ^{5}} d x

3 ln ∣ x ∣ + \frac{1}{x ^{4}} + C

Schritte zur Lösung

\int \frac{3}{x} - \frac{4}{x ^{5}} 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{3}{x} d x - \int \frac{4}{x ^{5}} d x

\int \frac{3}{x} d x = 3 ln ∣ x ∣

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

= 3 ln ∣ x ∣ - (- \frac{1}{x ^{4}})

Vereinfache

= 3 ln ∣ x ∣ + \frac{1}{x ^{4}}
