integral of (2x^3+7sqrt(x)+1/(x^3))

Lösung

\int (2 x^{3} + 7 x + \frac{1}{x ^{3}}) d x

\frac{x ^{4}}{2} + \frac{14}{3} x^{\frac{3}{2}} - \frac{1}{2 x ^{2}} + C

Schritte zur Lösung

\int 2 x^{3} + 7 x + \frac{1}{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 2 x^{3} d x + \int 7 x d x + \int \frac{1}{x ^{3}} d x

\int 2 x^{3} d x = \frac{x ^{4}}{2}

\int 7 x d x = \frac{14}{3} x^{\frac{3}{2}}

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

= \frac{x ^{4}}{2} + \frac{14}{3} x^{\frac{3}{2}} - \frac{1}{2 x ^{2}}
