integral of (7/x-6/(x^3))

Lösung

\int (\frac{7}{x} - \frac{6}{x ^{3}}) d x

7 ln ∣ x ∣ + \frac{3}{x ^{2}} + C

Schritte zur Lösung

\int \frac{7}{x} - \frac{6}{x ^{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{7}{x} d x - \int \frac{6}{x ^{3}} d x

\int \frac{7}{x} d x = 7 ln ∣ x ∣

\int \frac{6}{x ^{3}} d x = - \frac{3}{x ^{2}}

= 7 ln ∣ x ∣ - (- \frac{3}{x ^{2}})

Vereinfache

= 7 ln ∣ x ∣ + \frac{3}{x ^{2}}

Füge eine Konstante zur Lösung hinzu

= 7 ln ∣ x ∣ + \frac{3}{x ^{2}} + C

(x, y) \to (1, - 1) lim ((e^{- x y}) (cos (x + y)))
