\int_{0}^{π} 3 e^{x} + 8 sin (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_{0}^{π} 3 e^{x} d x + \int_{0}^{π} 8 sin (x) d x

\int_{0}^{π} 3 e^{x} d x = 3 (e^{π} - 1)

\int_{0}^{π} 8 sin (x) d x = 16

= 3 (e^{π} - 1) + 16

Vereinfache

3 (e^{π} - 1) + 16 : 3 e^{π} + 13

= 3 e^{π} + 13

\int_{2}^{4} - \frac{6}{x ^{2}} d x

\int_{0}^{\frac{a}{2}} sin^{2} (\frac{π x}{a}) d x

\int_{- 2}^{1} 3 + y^{2} d y

\int_{\frac{π}{6}}^{\frac{π}{4}} sin (4 t) d t

\int_{0}^{8} 9 e^{x} d x
