BesselJZero

BesselJZero[n, k]
represents the k^(th) zero of the Bessel function J_n(x).
BesselJZero[n, k, x0]
represents the k^(th) zero greater than x0.
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • N[BesselJZero[n, k]] gives a numerical approximation so long as the specified zero exists.
  • BesselJZero[n, k] represents the k^(th) zero greater than 0.
  • BesselJZero can be evaluated to arbitrary numerical precision.
