If we want to find x giving J_m(x)=0 where m=any constants, how can we analytically get x?

Thank you

I don't think you can do that analytically. (from memory)

I also use mathematica to solve but it doesn't help.

For large x, you can use the asymptotic formula for [tex]J_n(x)[/tex]. If I remember right, the difference between successive roots will tend to [itex]\pi[/itex] for large x.

Alternatively, you could look up tables which give the zeros for various Bessel functions in a mathematical handbook
