Schritte zur Lösung

\int_{- 4}^{4} 32 - x^{2} - x^{2} d x

Vereinfache

= \int_{- 4}^{4} 32 - 2 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_{- 4}^{4} 32 d x - \int_{- 4}^{4} 2 x^{2} d x

\int_{- 4}^{4} 32 d x = 256

\int_{- 4}^{4} 2 x^{2} d x = \frac{256}{3}

= 256 - \frac{256}{3}

Vereinfache

256 - \frac{256}{3} : \frac{512}{3}

= \frac{512}{3}

\int_{0}^{0.41} ln (1 + x^{2}) d x

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

\int_{π}^{2 π} \frac{1 + cos ( x )}{x} d x

\int_{\frac{1}{10}}^{\frac{11}{10}} \frac{1}{x} d x

\int_{4}^{5} \frac{1}{( y - 4 ) ^{\frac{1}{3}}} d y
