    equations don't converge

    and you list zero equations.

    my guess is, you mean which of the integrals have a finite value.  the best way to find that is to evaluate each one.

    I'll do one or two

    ∫tanxdx = –ln|cos u|  between 0 and π/2

    cos 0 = 1, –ln 1 = 0

    cos π/2 = 0, –ln 0 = undefined, so this does not have a finite value
