= \int_{0}^{x} t^{15} d t - \int_{0}^{x} 5 t^{13} d t + \int_{0}^{x} 10 t^{11} d t - \int_{0}^{x} 10 t^{9} d t + \int_{0}^{x} 5 t^{7} d t - \int_{0}^{x} t^{5} d t

\int_{0}^{x} t^{15} d t = \frac{x ^{16}}{16}

\int_{0}^{x} 5 t^{13} d t = \frac{5 x ^{14}}{14}

\int_{0}^{x} 10 t^{11} d t = \frac{5 x ^{12}}{6}

\int_{0}^{x} 10 t^{9} d t = x^{10}

\int_{0}^{x} 5 t^{7} d t = \frac{5 x ^{8}}{8}

\int_{0}^{x} t^{5} d t = \frac{x ^{6}}{6}

= \frac{x ^{16}}{16} - \frac{5 x ^{14}}{14} + \frac{5 x ^{12}}{6} - x^{10} + \frac{5 x ^{8}}{8} - \frac{x ^{6}}{6}
