Bimaximal (BM) and tri-bimaximal (TB) mixings of neutrinos are two special cases of lepton mixing matrix, which predict the reactor angle \(\theta_{13}=0\) and the atmospheric angle \(\tan^2\theta_{23}=1\). Recent precision measurements and global analysis of oscillation parameters, have confirmed a non-vanishing value of \(\theta_{13}\) as well as deviations of \(\theta_{12}\) and \(\theta_{23}\) from their maximal values predicted by BM or TB mixing. In this work we mainly concentrate on \(\theta_{13}\) and \(\theta_{23}\) to assign \(\sin\theta_{13}\neq 0\) and \(\tan^2\theta_{23}
