integral of ((2x)/(x^2-36)+1/x+7)

Lösung

\int (\frac{2 x}{x ^{2} - 36} + \frac{1}{x} + 7) d x

ln x^{2} - 36 + ln ∣ x ∣ + 7 x + C

Schritte zur Lösung

\int \frac{2 x}{x ^{2} - 36} + \frac{1}{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{2 x}{x ^{2} - 36} d x + \int \frac{1}{x} d x + \int 7 d x

\int \frac{2 x}{x ^{2} - 36} d x = ln x^{2} - 36

\int \frac{1}{x} d x = ln ∣ x ∣

\int 7 d x = 7 x

= ln x^{2} - 36 + ln ∣ x ∣ + 7 x

Füge eine Konstante zur Lösung hinzu

= ln x^{2} - 36 + ln ∣ x ∣ + 7 x + C

\int c

\frac{d y}{d x} = - 3 y^{\frac{2}{3}} sin (x)

x \to - \infty lim (\frac{3}{x})

\frac{\partial}{\partial x} (\frac{x y ^{2}}{z})

y = x^{2} ln (2 x + 1)
