\frac{6 x + 1}{4 x ^{2} + 4 x + 10} : \frac{6 x}{4 x ^{2} + 4 x + 10} + \frac{1}{4 x ^{2} + 4 x + 10}

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{6 x}{4 x ^{2} + 4 x + 10} d x + \int \frac{1}{4 x ^{2} + 4 x + 10} d x

\int \frac{6 x}{4 x ^{2} + 4 x + 10} d x = 3 (\frac{1}{4} ln 4 x^{2} + 4 x + 10 - \frac{1}{6} arctan (\frac{2}{3} x + \frac{1}{3}))

\int \frac{1}{4 x ^{2} + 4 x + 10} d x = \frac{1}{6} arctan (\frac{2}{3} x + \frac{1}{3})

= 3 (\frac{1}{4} ln 4 x^{2} + 4 x + 10 - \frac{1}{6} arctan (\frac{2}{3} x + \frac{1}{3})) + \frac{1}{6} arctan (\frac{2}{3} x + \frac{1}{3})

Vereinfache

3 (\frac{1}{4} ln 4 x^{2} + 4 x + 10 - \frac{1}{6} arctan (\frac{2}{3} x + \frac{1}{3})) + \frac{1}{6} arctan (\frac{2}{3} x + \frac{1}{3}) : \frac{3}{4} ln 4 x^{2} + 4 x + 10 - \frac{1}{3} arctan (\frac{2}{3} x + \frac{1}{3})

= \frac{3}{4} ln 4 x^{2} + 4 x + 10 - \frac{1}{3} arctan (\frac{2}{3} x + \frac{1}{3})
