integral of (50x+6)/((7x+1)(x-1))

Lösung

\int \frac{50 x + 6}{( 7 x + 1 ) ( x - 1 )} d x

Lösung

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

Schritte zur Lösung

\int \frac{50 x + 6}{( 7 x + 1 ) ( x - 1 )} d x

Ermittle den Partialbruch von

\frac{50 x + 6}{( 7 x + 1 ) ( x - 1 )} : \frac{1}{7 x + 1} + \frac{7}{x - 1}

= \int \frac{1}{7 x + 1} + \frac{7}{x - 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{1}{7 x + 1} d x + \int \frac{7}{x - 1} d x

\int \frac{1}{7 x + 1} d x = \frac{1}{7} ln ∣ 7 x + 1 ∣

\int \frac{7}{x - 1} d x = 7 ln ∣ x - 1 ∣

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

Füge eine Konstante zur Lösung hinzu

= \frac{1}{7} ln ∣ 7 x + 1 ∣ + 7 ln ∣ x - 1 ∣ + C
