Maclaurin's expansion

It is impossible to find all prime numbers, so Maclaurin's expansion is a good example to show convergence.

If x had a certain value, this mathematical formula would be convergence.
Then, you see complex number Z.



This complex plane don't include point at infinity, so it must be absolute convergence.



Z=X0 means expansion of the circle, and X0 is a radius of each circles.
