\int_{0}^{l n (18)} tanh (x) d x

Umschreiben mit Hilfe von Trigonometrie-Identitäten

= \int_{0}^{l n (18)} \frac{sinh ( x )}{cosh ( x )} d x

Wende U-Substitution an

= \int_{1}^{\frac{325}{36}} \frac{1}{u} d u

Nutze das gemeinsame Integral :

\int \frac{1}{u} d u = ln (∣ u ∣)

= [ln ∣ u ∣]_{1}^{\frac{325}{36}}

Berechne die Grenzen:
