Q1
Let \( g(x)=f(x)+f(1-x) \) and \( f^{\prime \prime}(x)>0, x \in(0,1) \). If
\( g \) is decreasing in the interval \( (0, \alpha) \) and increasing
in the interval \( (\alpha, 1) \), then the value of
\( \tan ^{-1}(2 \alpha)+\tan ^{-1}\left(\frac{1}{\alpha}\right)+\tan ^{-1}\left(\frac{\alpha+1}{\alpha}\right) \), is equal to
