Schritte zur Lösung

\int_{1}^{4} 4 x^{2} - 9 x 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}^{4} 4 x^{2} d x - \int_{1}^{4} 9 x d x

\int_{1}^{4} 4 x^{2} d x = 84

\int_{1}^{4} 9 x d x = \frac{135}{2}

= 84 - \frac{135}{2}

Vereinfache

84 - \frac{135}{2} : \frac{33}{2}

= \frac{33}{2}

\int_{0}^{4} (3 x - 7) d x

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

\int_{0}^{1} e^{- x} x d x

\int_{0}^{1 - x} (1 - x - y)^{2} d y

\int_{1}^{6} 5 x^{- 4} d x
