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
