\int_{0}^{3} - x^{2} + x^{2} - 4 x d x

- 18

Schritte zur Lösung

\int_{0}^{3} - x^{2} + x^{2} - 4 x d x

Vereinfache

= \int_{0}^{3} - 4 x d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - 4 \cdot \int_{0}^{3} x d x

Wende die Potenzregel an

= - 4 [\frac{x ^{2}}{2}]_{0}^{3}

Berechne die Grenzen:

\frac{9}{2}

= - 4 \cdot \frac{9}{2}

Vereinfache

= - 18

\int_{- π}^{π} cos (2 x) sin (2 x) d x

\int_{2}^{8} x e^{x^{2}} d x

\int_{0}^{0.2} 25 e^{- 5 x} d x

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

\int_{x^{2}}^{x^{4}} (t + t^{2})^{2} d t
