BesselJ
BesselJ[n, z]
gives the Bessel function of the first kind 
.
Details
- Mathematical function, suitable for both symbolic and numerical manipulation.
satisfies the differential equation 
. - BesselJ[n, z] has a branch cut discontinuity in the complex z plane running from
to 
. - FullSimplify and FunctionExpand include transformation rules for BesselJ.
- For certain special arguments, BesselJ automatically evaluates to exact values.
- BesselJ can be evaluated to arbitrary numerical precision.
- BesselJ automatically threads over lists.
