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

Entferne die Extremwerte

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

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

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

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

Vereinfache

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