Schritte zur Lösung

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

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

\int_{1}^{2} x^{2} d x = \frac{7}{3}

= 1 + \frac{7}{3}

Vereinfache

1 + \frac{7}{3} : \frac{10}{3}

= \frac{10}{3}

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

\int_{0}^{2} (4 x - 2) d x

\int_{- 4 π}^{π} cos^{2} (x) d x

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

\int_{0}^{π} - x cos (x) d x
