integral of 4x^3+3sqrt(x)+1/(x^3)

Lösung

\int 4 x^{3} + 3 x + \frac{1}{x ^{3}} d x

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

Schritte zur Lösung

\int 4 x^{3} + 3 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 4 x^{3} d x + \int 3 x d x + \int \frac{1}{x ^{3}} d x

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

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

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

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