integral from a to 2a of ax-(a^3)/x

Lösung

\int_{a}^{2 a} a x - \frac{a ^{3}}{x} d x

Lösung

a (2 a^{2} - \frac{a ^{2}}{2}) - ln (2) a^{3}

Schritte zur Lösung

\int_{a}^{2 a} a x - \frac{a ^{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_{a}^{2 a} a x d x - \int_{a}^{2 a} \frac{a ^{3}}{x} d x

\int_{a}^{2 a} a x d x = a (2 a^{2} - \frac{a ^{2}}{2})

\int_{a}^{2 a} \frac{a ^{3}}{x} d x = ln (2) a^{3}

= a (2 a^{2} - \frac{a ^{2}}{2}) - ln (2) a^{3}
