Exactly! That's it, mathematically speaking! However, when I try sage: sin(2 / (A((0.99, 1.01)) + dx + 3*dy)) ValueError: Can only apply sin to formal power series with zero constant term.
And, I get sage: A((0.99,1.01)) 1.0? but sage: sage: A(RIF(0.99,1.01)) 1.0? + O(dx, dy)^53 Shouldn't that give the same? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
