(x^{2} - 1)^{2} : x^{4} - 2 x^{2} + 1

= \int_{- 1}^{3} x^{4} - 2 x^{2} + 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_{- 1}^{3} x^{4} d x - \int_{- 1}^{3} 2 x^{2} d x + \int_{- 1}^{3} 1 d x

\int_{- 1}^{3} x^{4} d x = \frac{244}{5}

\int_{- 1}^{3} 2 x^{2} d x = \frac{56}{3}

\int_{- 1}^{3} 1 d x = 4

= \frac{244}{5} - \frac{56}{3} + 4

Vereinfache

\frac{244}{5} - \frac{56}{3} + 4 : \frac{512}{15}

= \frac{512}{15}

\int_{0}^{3} (3 - 2 x + 3 x^{2}) d x

\int_{- 2}^{1} ∣ x - 1 ∣ d x

\int_{2}^{3} 1 + x^{2} d x

\int_{0}^{\frac{1}{9}} x ln (9 x) d x

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