integral of (sec(2x)+tan(2x))

Lösung

\int (sec (2 x) + tan (2 x)) d x

\frac{1}{2} ln ∣ tan (2 x) + sec (2 x) ∣ - \frac{1}{2} ln ∣ cos (2 x) ∣ + C

Schritte zur Lösung

\int sec (2 x) + tan (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 sec (2 x) d x + \int tan (2 x) d x

\int sec (2 x) d x = \frac{1}{2} ln ∣ tan (2 x) + sec (2 x) ∣

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

= \frac{1}{2} ln ∣ tan (2 x) + sec (2 x) ∣ - \frac{1}{2} ln ∣ cos (2 x) ∣
