\int_{- 5}^{0} x 25 - x^{2} d x

Wende U-Substitution an

= \int_{0}^{25} - \frac{u}{2} d u

Entferne die Konstante:

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

= - \frac{1}{2} \cdot \int_{0}^{25} u d u

Wende die Potenzregel an

= - \frac{1}{2} [\frac{2}{3} u^{\frac{3}{2}}]_{0}^{25}

Berechne die Grenzen:

\frac{250}{3}

= - \frac{1}{2} \cdot \frac{250}{3}

Vereinfache

= - \frac{125}{3}

\int_{0}^{x^{2}} sin (θ^{2}) d θ

\int_{\infty}^{0} \frac{1}{3 - 4 x} d x

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

\int_{0}^{y} \frac{sin ( y )}{y} d y

\int_{0}^{2} 4 \cdot 2^{- x} - 1 d x
