He's clearly just leaving out some context, which in this case is clear (at least to me and based on the question). On Saturday, December 26, 2015, Volker Braun wrote: > The expected result of your code is "NameError: name 'G' is not defined" > and this is what I get > >

Re: [sage-support] Fwd: [sage-release] Bug in limit?

This definitely looks like a bug. In the meantime, a workaround is to use sympy: sage: var('m a0') (m, a0) sage: x=2/5*((3/4)^m - 1)*(a0 - 100) + 1/5*(3*(3/4)^m + 2)*a0;x 2/5*((3/4)^m - 1)*(a0 - 100) + 1/5*(3*(3/4)^m + 2)*a0 sage: limit(x, m=oo) [BAD] sage: limit(x, m=oo,
