    sir in simple question we used to check by rt–s² ..so it means if region will be given then we don't use that rt–s² concept

    eduncle-logo-app

    rt-s^2 concept is used when only f(x,y) is given and no region given .

    eduncle-logo-app

    here region is given , so we don't use rt-s^2 concept
