4

Schritte zur Lösung

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

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

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

= 4 + 0

= 4

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

\int_{2}^{3} (3 t + 2) d t

\int_{0}^{1} (\frac{3}{8}) x^{2} d x

\int_{π}^{0} - sin^{2} (x) d x

\int_{6}^{12} \frac{y}{y ^{2} - 2 y - 3} d y
