Schritte zur Lösung

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

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

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

\int_{0}^{1} 2 x d x = 1

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

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

Vereinfache

\frac{3}{4} - \frac{1}{3} + 1 - 4 : - \frac{31}{12}

= - \frac{31}{12}

\int_{0}^{1} \frac{32}{9} (x y)^{\frac{1}{3}} d y

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

\int_{0}^{5} (x + 6 - x^{2}) d x

\int_{0}^{\frac{π}{4}} e^{3 x} sin (2 x) d x

\int_{0}^{b} x e^{- a x} d x
