Radius of convergence

Summary

Each power series with center cc has a unique RR in [0,∞][0, \infty] such that it converges for ∣x−c∣<R|x - c| < R and diverges for ∣x−c∣>R|x - c| > R. This RR is its radius of convergence. The node radius of convergence gives the precise definition.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
