Ω = \underset{0}{\int^{\frac{π}{2}}} \tan^{- 1} \cos x d x

(I^{'} d need the exact value if possible . I^{'} ve

got no idea if and how this can be solved .)

{it}^{'} s possible to solve the integral but {it}^{'} s very

complicated and I {don}^{'} t think you could use

the exact value .

Ω \approx . 845291

www . wolframalpha . com gives the exact

indefinite integral which needs about 25

lines but only an approximate value for [0; π / 2]

Ok I see \dots
