Hi !
I'm trying to find the first n roots of an equation involving Bessel
Functions and to create a List of them.
The best thing I find so far is :
n = 10;
For[i = 0, i < n,
Print[FindRoot[- k BesselJ[1, k] + 30 BesselJ[0, k] == 0, {k,
2.32 + i Pi}]];
i++]
And the result I get is :
{k->3.2}
{k->5.2}
{k->8.3}
....
Does anyone know what {k->3.2} means ? And how I could get only the value
3.2 instead of {k->3.2} in order to create a list?
Thank you
