Yes but when you've actually studied Cauchy and winding number you'll look at 1/x^2 differently.

The irremovable singularities of e^x and ln x would also make your different handling of * and / as silly as treating + from - in any proof. The essential singular complex is a multiplicity of syptomatic indeterminates, discontinuities and dis-focused lack of convergence of result. There is only one to be analysed, and so is singular. Sticking to subjects I know? Umm? I do know you should stick to a fan (of the rotary variaty).

Nope .. it does not have to have all the answers .. even though any answer works. > They are all roots. Yes they are .. that what I just said .. it can have any finite value Try to keep up > Picking prefered roots is one thing, saying the whole divmul zero > complex is not the one problem is missing the point.

That's what I just said .. +ve or -ve. You're really very poor at comprehension. Perhaps more familiarity with the topic would help? > > None of those are examples of a singularity. > > > Now .. if you said f(x) = 1/x, then you get a singularity at x = 0. > > > Maybe you should stick to subjects you know and understand ... are > > there any? > > Yes but when you've actually studied Cauchy and winding number you'll > look at 1/x^2 differently. I have an honors degree in mathematics .. I understand it far better that your apparent limited grasp.

You have no idea of maths nor the meaning of the terms you are stringing together. Learn some maths, then come back .. and try to at least post something coherent next time.

No, my comprehension is excellent, I very poor at being your underdog ;-) > > > None of those are examples of a singularity. > > > > Now .. if you said f(x) = 1/x, then you get a singularity at x = 0. > > > > Maybe you should stick to subjects you know and understand ... are > > > there any? > > > Yes but when you've actually studied Cauchy and winding number you'll > > look at 1/x^2 differently. > > I have an honors degree in mathematics ..
