| 2012-04-05 04:06:26 +0200 | asked a question | Getting a function from a symbolic expression (i.e. "y = x+2") Hi all, I'm having trouble understanding how to solve the following problem. Let's say, for instance, that I have an expression a = y - 2 == x If I wish to solve this for y, b = solve(a, y) This returns another object of type Expression that looks like "y = x + 2" My question is, is it possible to obtain a callable symbolic expression x --> x + 2 from this result, b? I'm trying to solve an implicit equation for a variable and obtain a plottable/differentiable etc. result |
