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

Lösung

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

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

Schritte zur Lösung

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

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

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

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

Füge eine Konstante zur Lösung hinzu

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

x \to 0 lim (5 + \frac{9}{x ^{3}})

\frac{x d y}{d x} + y = 6 x + 1

\int \frac{csc ^{2} ( x )}{cot ^{7} ( x )} d x
