Schritte zur Lösung

\int_{0}^{1} x^{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_{0}^{1} x^{3} d x - \int_{0}^{1} 4 x^{2} d x

\int_{0}^{1} x^{3} d x = \frac{1}{4}

\int_{0}^{1} 4 x^{2} d x = \frac{4}{3}

= \frac{1}{4} - \frac{4}{3}

Vereinfache

\frac{1}{4} - \frac{4}{3} : - \frac{13}{12}

= - \frac{13}{12}

\int_{- 1}^{2} (9 x^{2} - 4 x + 5) d x

\int_{- 4}^{4} (- x^{2} + 16) d x

\int_{1}^{5} (5 + \frac{1}{x} + e^{x}) d x

\int_{4.9}^{7.1} (12 x^{2} - 6 x + 4) d x

\int_{1}^{3} (2 x^{2} - 8) d x
