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

= \int_{1}^{e} x + \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}^{e} x d x + \int_{1}^{e} \frac{1}{x} d x

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

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

= \frac{e ^{2} - 1}{2} + 1

x \to 4 + lim (ln (x^{2} - 16))

\frac{1}{2} y^{^{'}} + y = 0, y (1) = 1
