integral of (3x^2-2/(x^3)+\sqrt[3]{x}-8)

Lösung

\int (3 x^{2} - \frac{2}{x ^{3}} + 3 x - 8) d x

x^{3} + \frac{1}{x ^{2}} + \frac{3}{4} x^{\frac{4}{3}} - 8 x + C

Schritte zur Lösung

\int 3 x^{2} - \frac{2}{x ^{3}} + 3 x - 8 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 3 x^{2} d x - \int \frac{2}{x ^{3}} d x + \int 3 x d x - \int 8 d x

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

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

\int 3 x d x = \frac{3}{4} x^{\frac{4}{3}}

\int 8 d x = 8 x

= x^{3} - (- \frac{1}{x ^{2}}) + \frac{3}{4} x^{\frac{4}{3}} - 8 x

Vereinfache

= x^{3} + \frac{1}{x ^{2}} + \frac{3}{4} x^{\frac{4}{3}} - 8 x
