integral of (4/x+9/(x^7))

Lösung

\int (\frac{4}{x} + \frac{9}{x ^{7}}) d x

4 ln ∣ x ∣ - \frac{3}{2 x ^{6}} + C

Schritte zur Lösung

\int \frac{4}{x} + \frac{9}{x ^{7}} 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{4}{x} d x + \int \frac{9}{x ^{7}} d x

\int \frac{4}{x} d x = 4 ln ∣ x ∣

\int \frac{9}{x ^{7}} d x = - \frac{3}{2 x ^{6}}

= 4 ln ∣ x ∣ - \frac{3}{2 x ^{6}}

Füge eine Konstante zur Lösung hinzu

= 4 ln ∣ x ∣ - \frac{3}{2 x ^{6}} + C

\int \frac{1}{( sin ( x ) + tan ( x ) )} d x

\frac{\partial}{\partial x} (1 - y^{2})

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

h \to 0 lim (\frac{( 1 + h ) ^{8} - 1}{h})

\int ln (2 x + 3) d x
