Module j1f 

Functions

f_j1f

Bessel of the first kind of order 1

j1f_asympt 🔒

j1f_asympt_alpha 🔒

Note expansion generation below: this is negative series expressed in Sage as positive, so before any real evaluation x=1/x should be applied.

j1f_asympt_beta 🔒

Note expansion generation below: this is negative series expressed in Sage as positive, so before any real evaluation x=1/x should be applied

j1f_rsqrt 🔒

poly_near_zero 🔒

Generated in Sollya:

small_argument_path 🔒

This method on small range searches for nearest zero or extremum. Then picks stored series expansion at the point end evaluates the poly at the point.
