y (- 1 + y + e - e^{y}) : - y + y^{2} + ey - e^{y} y

= \int_{0}^{1} - y + y^{2} + ey - e^{y} y d y

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= - \int_{0}^{1} y d y + \int_{0}^{1} y^{2} d y + \int_{0}^{1} ey d y - \int_{0}^{1} e^{y} y d y

\int_{0}^{1} y d y = \frac{1}{2}

\int_{0}^{1} y^{2} d y = \frac{1}{3}

\int_{0}^{1} ey d y = \frac{e}{2}

\int_{0}^{1} e^{y} y d y = 1

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