(t^{2} + 2)^{3} : t^{6} + 6 t^{4} + 12 t^{2} + 8

= \int t^{6} + 6 t^{4} + 12 t^{2} + 8 d t

Wende die Summenregel an:

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

= \int t^{6} d t + \int 6 t^{4} d t + \int 12 t^{2} d t + \int 8 d t

\int t^{6} d t = \frac{t ^{7}}{7}

\int 6 t^{4} d t = \frac{6 t ^{5}}{5}

\int 12 t^{2} d t = 4 t^{3}

\int 8 d t = 8 t

= \frac{t ^{7}}{7} + \frac{6 t ^{5}}{5} + 4 t^{3} + 8 t
