Schritte zur Lösung

\int_{1}^{2} \frac{1}{x} - \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_{1}^{2} \frac{1}{x} d x - \int_{1}^{2} \frac{1}{x ^{2}} d x

\int_{1}^{2} \frac{1}{x} d x = ln (2)

\int_{1}^{2} \frac{1}{x ^{2}} d x = \frac{1}{2}

= ln (2) - \frac{1}{2}

x \to 0 lim (6 x - 1)

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

\int cos (ln (7 x)) d x

x \to 0 lim (- x^{6})

x \to 4 - lim (\frac{x}{x + 4})
