Schritte zur Lösung

\int_{1}^{9} x^{2} + 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_{1}^{9} x^{2} d x + \int_{1}^{9} 2 d x

\int_{1}^{9} x^{2} d x = \frac{728}{3}

\int_{1}^{9} 2 d x = 16

= \frac{728}{3} + 16

Vereinfache

\frac{728}{3} + 16 : \frac{776}{3}

= \frac{776}{3}

\int_{s i n (x)}^{1} 1 + x^{2} d x

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

\int_{0}^{3} \frac{1}{9 - x ^{2}} d x

\int_{1}^{3} f (t) d t
