NumericalMath`BesselZeros`
New function BesselJZero has been added to the built-in Mathematica kernel.
New function BesselYZero has been added to the built-in Mathematica kernel.
Evaluate the 5 th zero of the Bessel function 
numerically:
![<< NumericalMath`BesselZeros`;
BesselJZeros[0, 5]](Files/BesselZeros.en/legacy_1.gif){kind=small}
Similarly, evaluate the 1 st zero of the Bessel function 
numerically:
![<< NumericalMath`BesselZeros`;
BesselYZeros[0, 1]](Files/BesselZeros.en/legacy_2.gif){kind=small}
These functions were available in previous versions of Mathematica and are now available on the web at library.wolfram.com/infocenter/MathSource/6777:
