Schritte zur Lösung

\int_{1}^{6} x^{2} - 7 x + 6 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}^{6} x^{2} d x - \int_{1}^{6} 7 x d x + \int_{1}^{6} 6 d x

\int_{1}^{6} x^{2} d x = \frac{215}{3}

\int_{1}^{6} 7 x d x = \frac{245}{2}

\int_{1}^{6} 6 d x = 30

= \frac{215}{3} - \frac{245}{2} + 30

Vereinfache

\frac{215}{3} - \frac{245}{2} + 30 : - \frac{125}{6}

= - \frac{125}{6}

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

\int_{1}^{8} \frac{3 ( ln ( x ) ) ^{2}}{x} d x

\int_{l n (2)}^{l n (4)} \frac{e ^{- x}}{1 - e ^{- 2 x}} d x

\int_{1}^{3} (x + 1) e^{x^{2} + 2 x} d x

\int_{- 2}^{2} - x^{2} - 2 d x
