(1 - x^{4})^{11} : 1 - 11 x^{4} + 55 x^{8} - 165 x^{12} + 330 x^{16} - 462 x^{20} + 462 x^{24} - 330 x^{28} + 165 x^{32} - 55 x^{36} + 11 x^{40} - x^{44}

= \int_{0}^{1} 1 - 11 x^{4} + 55 x^{8} - 165 x^{12} + 330 x^{16} - 462 x^{20} + 462 x^{24} - 330 x^{28} + 165 x^{32} - 55 x^{36} + 11 x^{40} - x^{44} d x

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} 1 d x - \int_{0}^{1} 11 x^{4} d x + \int_{0}^{1} 55 x^{8} d x - \int_{0}^{1} 165 x^{12} d x + \int_{0}^{1} 330 x^{16} d x - \int_{0}^{1} 462 x^{20} d x + \int_{0}^{1} 462 x^{24} d x - \int_{0}^{1} 330 x^{28} d x + \int_{0}^{1} 165 x^{32} d x - \int_{0}^{1} 55 x^{36} d x + \int_{0}^{1} 11 x^{40} d x - \int_{0}^{1} x^{44} d x

\int_{0}^{1} 1 d x = 1
