\int_{0}^{1} \frac{x ^{15}}{x ^{8} + 1} d x

Lange Division

\frac{x ^{15}}{x ^{8} + 1} : x^{7} - \frac{x ^{7}}{x ^{8} + 1}

= \int_{0}^{1} x^{7} - \frac{x ^{7}}{x ^{8} + 1} 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}^{1} x^{7} d x - \int_{0}^{1} \frac{x ^{7}}{x ^{8} + 1} d x

\int_{0}^{1} x^{7} d x = \frac{1}{8}

\int_{0}^{1} \frac{x ^{7}}{x ^{8} + 1} d x = \frac{1}{8} ln (2)

= \frac{1}{8} - \frac{1}{8} ln (2)

\int_{0}^{1} (1 - x^{4})^{7} d x

\int_{1}^{4} (2 x - 1)^{5} d x

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

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

\int_{0}^{3} cos (π x) d x
