Entferne die Extremwerte

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

\int_{- 2}^{0} 2 x^{2} - 2 x d x = \frac{28}{3}

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

\int_{1}^{2} 2 x^{2} - 2 x d x = \frac{5}{3}

= \frac{28}{3} + \frac{1}{3} + \frac{5}{3}

Vereinfache

\frac{28}{3} + \frac{1}{3} + \frac{5}{3} : \frac{34}{3}

= \frac{34}{3}

\int_{0}^{x} f (t) d t

f (x) = \frac{3}{1 + x ^{2}}

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

y^{^{'}} = 2 y, y (0) = 1
