BesselY[n, z]
gives the Bessel function of the second kind Y_n(z).
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • Y_n(z) satisfies the differential equation z^2​y^(′′)+z​y^′+(z^2-n^2)​y=0.
  • BesselY[n, z] has a branch cut discontinuity in the complex z plane running from -∞ to 0.
  • For certain special arguments, BesselY automatically evaluates to exact values.
  • BesselY can be evaluated to arbitrary numerical precision.
  • BesselY automatically threads over lists.
