\int_{- 2}^{2} 3 + 4 - x^{2} 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_{- 2}^{2} 3 d x + \int_{- 2}^{2} 4 - x^{2} d x

\int_{- 2}^{2} 3 d x = 12

\int_{- 2}^{2} 4 - x^{2} d x = 2 π

= 12 + 2 π

\int_{0}^{π} cos (x^{2}) d x

\int_{0}^{1} y e^{x y} d x

\int_{0}^{x^{2}} (1 - t) e^{t^{2}} d t

\int_{0}^{3} x^{2} + 2 d x

\int_{0}^{\frac{π}{4}} sin (x) - cos (x) d x
