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

\frac{a ^{3}}{2} - \frac{a ^{3}}{3}

Schritte zur Lösung

\int_{0}^{a} a x - 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_{0}^{a} a x d x - \int_{0}^{a} x^{2} d x

\int_{0}^{a} a x d x = \frac{a ^{3}}{2}

\int_{0}^{a} x^{2} d x = \frac{a ^{3}}{3}

= \frac{a ^{3}}{2} - \frac{a ^{3}}{3}

\int_{- 5}^{0} sin (\frac{nπ x}{5}) d x

\int_{1}^{2} [\frac{in x}{x ^{2}}] d x

\int_{0}^{t} sin (t - u) sin (u) d u

\int_{- 2}^{1} 6 - x^{2} d x

\int_{0}^{5} \frac{1}{x ^{0.5}} d x
