2014-09-26 10:53:20 +0200 | asked a question | plotting: value error variable not found Hi, I'm new to sage and hope that anybody can help me. I tried to plot two functions X1 and X2 which both depend on several parameters (k, j0, j1, jMax, a0, aMax, a1, v0, v1, vMax, x). I chose a value for every variable except for vMax because I wantet to plot X1 and X2 as a function of vMax. So I typed and it worked just fine. I wanted to do exactely the same with funktion X2, but then I got an value error: I don't know, why vMax is not found, as the function is definitely dependent of it. Moreover, with function X1 it just worked as expected! Yeah, sure, I should add some more details. I constructed X1 and X2 recursively as they are the way X, which is the integral of the acceleration a, which is the integral of the velocity v and so on. In the end, I get (more) |
