(7 - x) (x - 10) : 17 x - x^{2} - 70

= \int_{7}^{10} 17 x - x^{2} - 70 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_{7}^{10} 17 x d x - \int_{7}^{10} x^{2} d x - \int_{7}^{10} 70 d x

\int_{7}^{10} 17 x d x = \frac{867}{2}

\int_{7}^{10} x^{2} d x = 219

\int_{7}^{10} 70 d x = 210

= \frac{867}{2} - 219 - 210

Vereinfache

\frac{867}{2} - 219 - 210 : \frac{9}{2}

= \frac{9}{2}

\int_{0}^{1} (2 x^{e} + 5 e^{x}) d x

\int_{1}^{\frac{1 + 5}{2}} \frac{1}{x} d x

\int_{1}^{9} t (1 + t) d t
