Hi,
Bill Page reported this issue, which I'm copying here to the
sage-support list, in the hopes somebody will look into it:
sage: var('k, l')
sage: f = real(cosh(sqrt(1/2*k-1/2*sqrt(k^2+4l))))
sage: g =
f.substitute_expression(imag_part(k)==0,imag_part(l)==0,real_part(k)==k,real_part(l)==l)
# the above is all fine. Then:
sage: g.full_simplify()
---------------------------------------------------------------------------
