integral of (1/(x^2)+4/(xsqrt(x))+2)

Lösung

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

- \frac{1}{x} - \frac{8}{x} + 2 x + C

Schritte zur Lösung

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

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

\int \frac{4}{x x} d x = - \frac{8}{x}

\int 2 d x = 2 x

= - \frac{1}{x} - \frac{8}{x} + 2 x

= - \frac{1}{x} - \frac{8}{x} + 2 x + C

\frac{d}{d x} (\frac{3 x}{x ^{2} - 1})
