x (x + 4)^{2} : x^{3} + 8 x^{2} + 16 x

= \int_{- 1}^{1} x^{3} + 8 x^{2} + 16 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_{- 1}^{1} x^{3} d x + \int_{- 1}^{1} 8 x^{2} d x + \int_{- 1}^{1} 16 x d x

\int_{- 1}^{1} x^{3} d x = 0

\int_{- 1}^{1} 8 x^{2} d x = \frac{16}{3}

\int_{- 1}^{1} 16 x d x = 0

= 0 + \frac{16}{3} + 0

= \frac{16}{3}

\int_{0}^{\frac{π}{2}} sec (x) tan (x) d x

\int_{1}^{4} ln (2 x) d x

\int_{- 1}^{4} 2 x d x

\int_{1}^{4} (3 x^{2} - 2)^{3} d x

\int_{0}^{3} \frac{1}{( 1 + x ) x} d x
