I am taking a complex analysis course, and well, its 2complex4me! So here are my questions...
I need to find the radius of convergence of the following complex power series: (so naturally z is in C here).
My apologies for not using nice looking math typeset, but I dont know the code for it.
The mth order Bessel function:
Jm(z) = sum[ {((-1)^n) ((z/2)^(m+2n))} / {n!(n+m)!} , n=0, n=infinity ]
Also
sum[ z^n!, n=0, n=inf ]
And
sum[ (n+a^n)z^n, n=0, n=inf ]
I will undoubtedly have more questions as I progress in the course, but if someone can help me out here, I would be very greatful!
Thank you, Damian.
