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

Lösung

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

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

Schritte zur Lösung

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

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

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

\int 8 e^{x} d x = 8 e^{x}

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

Füge eine Konstante zur Lösung hinzu

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

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

\int \frac{7}{x + 5} d x

\int x coth (x^{2}) d x

\int x (x^{2} + 1)^{\frac{3}{4}} d x

\int x ln (\frac{1 + 2 x}{1 - 2 x}) d x
