Wende die partielle Integration an

= e^{7 x} x - \int \frac{7}{2} e^{7 x} x d x

\int \frac{7}{2} e^{7 x} x d x = \frac{1}{7} (7 e^{7 x} x - 2 (7 e^{7 x} x - e^{7 x}))

= e^{7 x} x - \frac{1}{7} (7 e^{7 x} x - 2 (7 e^{7 x} x - e^{7 x}))

Vereinfache

e^{7 x} x - \frac{1}{7} (7 e^{7 x} x - 2 (7 e^{7 x} x - e^{7 x})) : \frac{2}{7} e^{7 x} x - \frac{2}{7} e^{7 x}

= \frac{2}{7} e^{7 x} x - \frac{2}{7} e^{7 x}
