integral of (2/(e^{-x)}-1/(2x))

Lösung

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

2 e^{x} - \frac{1}{2} ln ∣ x ∣ + C

Schritte zur Lösung

\int \frac{2}{e ^{- x}} - \frac{1}{2 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{2}{e ^{- x}} d x - \int \frac{1}{2 x} d x

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

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

= 2 e^{x} - \frac{1}{2} ln ∣ x ∣
