Schritte zur Lösung

\int_{2}^{5} 7 - 3 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}^{5} 7 d x - \int_{2}^{5} 3 x d x

\int_{2}^{5} 7 d x = 21

\int_{2}^{5} 3 x d x = \frac{63}{2}

= 21 - \frac{63}{2}

Vereinfache

21 - \frac{63}{2} : - \frac{21}{2}

= - \frac{21}{2}

\int_{1}^{2} 3 x^{2} + x d x

\int_{4}^{4} 1

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

\int_{0}^{\frac{2}{11}} \frac{1}{121 x ^{2} + 4} d x

\int_{0}^{l n (2)} 3 e^{3 x} d x
