Schritte zur Lösung

\int_{0}^{1} x 1 + x^{2} d x

Wende U-Substitution an

= \int_{1}^{2} u^{2} d u

Wende die Potenzregel an

= [\frac{u ^{3}}{3}]_{1}^{2}

Berechne die Grenzen:

\frac{2 2}{3} - \frac{1}{3}

= \frac{2 2}{3} - \frac{1}{3}

Vereinfache

= \frac{2 2 - 1}{3}

\int_{1}^{2} (- x^{2} + 5) d x

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

\int_{x}^{1} e^{- y^{2}} d y

\int_{- 3}^{4} \frac{1}{2} x d x

\int_{1}^{5} (x^{3} + x^{2} - x + 2) d x
