[SOLVED] Convergence of a series
I have a question that I can't do...can anybody help me?
Investigate the convergence of the series (in the complex plane) for difference values of a and b:
Generalise your solution by determining what constraints are required on the values of a and b, so as to guarantee the convergence of the series?
Thanks if you can help.
Sorry, still trying to understand
But I thought a + bi is a complex number.
i.e. b is not real.
so b could be a complex number?
So the assumption was that a and b are real numbers i.e.
it is not of the form a + (c +di)i
that's what I now understand of that that assumption is assuming.
Is this correct?
you're right, that was a stupid question.
