I am looking to use solve() or find_root() with a function defined using elliptic_kc (sage.functions.special.EllipticKC), however Sage produces an error. The context of this is for use in a coplanar waveguide impedance calculation.
Example:
sage: find_root(elliptic_kc(x)==2, x, 0, 0.5)
[...]
'TypeError: unable to simplify to float approximation'.
and
sage: solve(2.0==elliptic_kc(x), x, to_poly_solve=True)
[...]
TypeError: 'sage.symbolic.expression.Expression' object is not subscriptable
Is there a convenient way to perform a solve/numerical root for these special functions?
