integral of (2x^5-x^3-1)/(x^3-4x)

Lösung

\int \frac{2 x ^{5} - x ^{3} - 1}{x ^{3} - 4 x} d x

Lösung

\frac{2 x ^{3}}{3} + 7 x + \frac{1}{4} ln ∣ x ∣ - \frac{57}{8} ln ∣ x + 2 ∣ + \frac{55}{8} ln ∣ x - 2 ∣ + C

Schritte zur Lösung

\int \frac{2 x ^{5} - x ^{3} - 1}{x ^{3} - 4 x} d x

Lange Division

\frac{2 x ^{5} - x ^{3} - 1}{x ^{3} - 4 x} : 2 x^{2} + 7 + \frac{28 x - 1}{x ^{3} - 4 x}

= \int 2 x^{2} + 7 + \frac{28 x - 1}{x ^{3} - 4 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 2 x^{2} d x + \int 7 d x + \int \frac{28 x - 1}{x ^{3} - 4 x} d x

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

\int 7 d x = 7 x

\int \frac{28 x - 1}{x ^{3} - 4 x} d x = \frac{1}{4} ln ∣ x ∣ - \frac{57}{8} ln ∣ x + 2 ∣ + \frac{55}{8} ln ∣ x - 2 ∣

= \frac{2 x ^{3}}{3} + 7 x + \frac{1}{4} ln ∣ x ∣ - \frac{57}{8} ln ∣ x + 2 ∣ + \frac{55}{8} ln ∣ x - 2 ∣

= \frac{2 x ^{3}}{3} + 7 x + \frac{1}{4} ln ∣ x ∣ - \frac{57}{8} ln ∣ x + 2 ∣ + \frac{55}{8} ln ∣ x - 2 ∣ + C
