After exploring the wealth of math functions and polynomials on the HP Prime emulator, I noticed that the following functions were missing:

1) Bessel functions

2) Bernoulli numbers

3) Bernoulli polynomials

The history of HP calculator has supported calculating some of the Bessel functions, of integer orders, in the Math Pacs of various vintage calculators (in fact I was playing with the HP-67 Math Pac today and calculating Bessel function values). The Bernoulli numbers and polynomials have never been implemented in any HP calculator math pac. I am asking about these functions since the Prime now supports, for the first time, various orthogonal polynomials (Laguerre, Legendre, Hermite, and Chebyshev). So why not add Bessel and Bernoulli functions as new functions???
