y^{4} (1 - y)^{3} : y^{4} - 3 y^{5} + 3 y^{6} - y^{7}

= \int y^{4} - 3 y^{5} + 3 y^{6} - y^{7} 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 y^{4} d y - \int 3 y^{5} d y + \int 3 y^{6} d y - \int y^{7} d y

\int y^{4} d y = \frac{y ^{5}}{5}

\int 3 y^{5} d y = \frac{y ^{6}}{2}

\int 3 y^{6} d y = \frac{3 y ^{7}}{7}

\int y^{7} d y = \frac{y ^{8}}{8}

= \frac{y ^{5}}{5} - \frac{y ^{6}}{2} + \frac{3 y ^{7}}{7} - \frac{y ^{8}}{8}
