t^{3} (7 + t^{4})^{3} : 343 t^{3} + 147 t^{7} + 21 t^{11} + t^{15}

= \int 343 t^{3} + 147 t^{7} + 21 t^{11} + t^{15} 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 343 t^{3} d t + \int 147 t^{7} d t + \int 21 t^{11} d t + \int t^{15} d t

\int 343 t^{3} d t = \frac{343 t ^{4}}{4}

\int 147 t^{7} d t = \frac{147 t ^{8}}{8}

\int 21 t^{11} d t = \frac{7 t ^{12}}{4}

\int t^{15} d t = \frac{t ^{16}}{16}

= \frac{343 t ^{4}}{4} + \frac{147 t ^{8}}{8} + \frac{7 t ^{12}}{4} + \frac{t ^{16}}{16}
