\frac{2 ( y + 2 ) ^{\frac{3}{2}} - 2 ( y + 1 ) ^{\frac{3}{2}}}{3}

Schritte zur Lösung

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

Wende U-Substitution an

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

Wende die Potenzregel an

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

Berechne die Grenzen:

\frac{2}{3} (y + 2)^{\frac{3}{2}} - \frac{2}{3} (y + 1)^{\frac{3}{2}}

= \frac{2}{3} (y + 2)^{\frac{3}{2}} - \frac{2}{3} (y + 1)^{\frac{3}{2}}

Vereinfache

= \frac{2 ( y + 2 ) ^{\frac{3}{2}} - 2 ( y + 1 ) ^{\frac{3}{2}}}{3}

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

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

\int_{0}^{1} [e^{5 x + 3}] d x

\int_{- \infty}^{0} 1 3^{x} d x

\int_{0}^{\frac{π}{2}} (x - cos (y)) d y
