BesselYZero

BesselYZero[n,k]

represents the k^(th) zero of the Bessel function of the second kind .

BesselYZero[n,k,x0]

represents the k^(th) zero greater than x0.

Details

  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • N[BesselYZero[n,k]] gives a numerical approximation so long as the specified zero exists.
  • BesselYZero[n,k] represents the k^(th) zero greater than 0.
  • BesselYZero can be evaluated to arbitrary numerical precision.
  • BesselYZero automatically threads over lists. »
