\frac{1 + sin ^{2} ( x )}{x} : \frac{1}{x} + \frac{sin ^{2} ( x )}{x}

= \int \frac{1}{x} + \frac{sin ^{2} ( x )}{x} 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 \frac{1}{x} d x + \int \frac{sin ^{2} ( x )}{x} d x

\int \frac{1}{x} d x = 2 x

\int \frac{sin ^{2} ( x )}{x} d x = \frac{1}{2} (2 x - π C (2 \frac{2}{π} x))

= 2 x + \frac{1}{2} (2 x - π C (2 \frac{2}{π} x))

Vereinfache

2 x + \frac{1}{2} (2 x - π C (2 \frac{2}{π} x)) : 3 x - \frac{π}{2} C (2 \frac{2}{π} x)

= 3 x - \frac{π}{2} C (2 \frac{2}{π} x)
