\frac{8 - x ^{2}}{x ^{3}} : \frac{8}{x ^{3}} - \frac{1}{x}

= \int_{1}^{2} \frac{8}{x ^{3}} - \frac{1}{x} 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{8}{x ^{3}} d x - \int_{1}^{2} \frac{1}{x} d x

\int_{1}^{2} \frac{8}{x ^{3}} d x = 3

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

= 3 - ln (2)

x \to 0 lim (\frac{\frac{2}{x + 2} - 1}{x})

e^{t^{2}} y^{^{'}} + t + t y^{2} = 0

x \to 0 + lim (5 x^{2} ln (x))
