integral of (8x^3+2/(x^2))

Lösung

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

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

Schritte zur Lösung

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

\int 8 x^{3} d x = 2 x^{4}

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

= 2 x^{4} - \frac{2}{x}

Füge eine Konstante zur Lösung hinzu

= 2 x^{4} - \frac{2}{x} + C

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

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

\int (7 x^{3} + 4 3 x^{2}) d x

\int (x^{2} + 1) \cdot e^{x} d x

\int \frac{11 x + 2}{2 x ^{2} - 5 x - 3} d x
