\frac{x ^{2} + 6}{x ^{2}} : 1 + \frac{6}{x ^{2}}

= \int_{6}^{8} 1 + \frac{6}{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_{6}^{8} 1 d x + \int_{6}^{8} \frac{6}{x ^{2}} d x

\int_{6}^{8} 1 d x = 2

\int_{6}^{8} \frac{6}{x ^{2}} d x = \frac{1}{4}

= 2 + \frac{1}{4}

Vereinfache

2 + \frac{1}{4} : \frac{9}{4}

= \frac{9}{4}

x \to 2 lim (lo g_{4} (x - 2))

\frac{d y}{d x} + 3 x^{2} y = x^{2}

\frac{d y}{d x} = 10 x e^{5 y}
