Trigonometrische Substitution anwenden

= \int_{0}^{a r c t a n (5)} sec^{3} (u) d u

Wende integrale Reduktion an

= [\frac{sec ^{2} ( u ) sin ( u )}{2}]_{0}^{a r c t a n (5)} + \frac{1}{2} \cdot \int_{0}^{a r c t a n (5)} sec (u) d u

\int_{0}^{a r c t a n (5)} sec (u) d u = ln (5 + 26)

= [\frac{sec ^{2} ( u ) sin ( u )}{2}]_{0}^{a r c t a n (5)} + \frac{1}{2} ln (5 + 26)

Vereinfache

[\frac{sec ^{2} ( u ) sin ( u )}{2}]_{0}^{a r c t a n (5)} + \frac{1}{2} ln (5 + 26) : [\frac{1}{2} sec (u) tan (u)]_{0}^{a r c t a n (5)} + \frac{1}{2} ln (5 + 26)

= [\frac{1}{2} sec (u) tan (u)]_{0}^{a r c t a n (5)} + \frac{1}{2} ln (5 + 26)
