\int_{3}^{5} - x^{2} + 7 x - 10 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_{3}^{5} x^{2} d x + \int_{3}^{5} 7 x d x - \int_{3}^{5} 10 d x

\int_{3}^{5} x^{2} d x = \frac{98}{3}

\int_{3}^{5} 7 x d x = 56

\int_{3}^{5} 10 d x = 20

= - \frac{98}{3} + 56 - 20

Vereinfache

- \frac{98}{3} + 56 - 20 : \frac{10}{3}

= \frac{10}{3}

\int_{0}^{2 π} cos^{2} (θ) sin (θ) d θ

\int_{- π}^{π} e^{x} cos (x) d x

\int_{0}^{9} 2 x (x + x) d x

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