Schritte zur Lösung

\int_{1}^{4} 4 x^{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_{1}^{4} 4 x^{2} d x + \int_{1}^{4} x d x

\int_{1}^{4} 4 x^{2} d x = 84

\int_{1}^{4} x d x = \frac{14}{3}

= 84 + \frac{14}{3}

Vereinfache

84 + \frac{14}{3} : \frac{266}{3}

= \frac{266}{3}

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

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

\int_{1}^{2} 2 x + 5 d x

\int_{1}^{6} 2 x + \frac{1}{x} d x

\int_{- \frac{π}{6}}^{\frac{π}{6}} 2 sec^{2} (x) d x
