Schritte zur Lösung

\int_{4}^{9} 4 x^{2} - 15 x + 7 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}^{9} 4 x^{2} d x - \int_{4}^{9} 15 x d x + \int_{4}^{9} 7 d x

\int_{4}^{9} 4 x^{2} d x = \frac{2660}{3}

\int_{4}^{9} 15 x d x = \frac{975}{2}

\int_{4}^{9} 7 d x = 35

= \frac{2660}{3} - \frac{975}{2} + 35

Vereinfache

\frac{2660}{3} - \frac{975}{2} + 35 : \frac{2605}{6}

= \frac{2605}{6}

\int_{1}^{6} 2 π y (6 - y) d y

\int_{1}^{\infty} \frac{1}{x + 4} d x

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

\int_{e}^{e^{3}} \frac{1}{x ( ln ( x ) ) ^{3}} d x

\int_{0}^{1} 9 - 12 x + 4 x^{2} d x
