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

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

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

\int \frac{1}{x ( x - 1 ) ^{2}} d x = ln ∣ x ∣ - ln ∣ x - 1 ∣ - \frac{1}{x - 1}

= - \frac{2}{x - 1} - (ln ∣ x ∣ - ln ∣ x - 1 ∣ - \frac{1}{x - 1})

Vereinfache

= - \frac{1}{x - 1} - ln ∣ x ∣ + ln ∣ x - 1 ∣

\int e^{t y} d y

\frac{d ^{2} y}{d x ^{2}} + \frac{d y}{d x} + y = 0

\int \frac{x}{x + 7} d x

y^{^{''}} + 4 y = 4 sec (2 t)
