AiryBiZero

AiryBiZero[k]

represents the k^(th) zero of the Airy function TemplateBox[{x}, AiryBi].

AiryBiZero[k,x0]

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

Details

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