Hi Smath Team, I would like to change value of variable after I change an equation. However, new equation uses value of variable at time of equation definition. I saw discussions on this topic however, they did not help my situation. Please see attachment. Rob

You need to switch the definitions to "optimization numeric" in the context menu (right mouse button). You can see what definition you actually create by hovering with the mouse over the math region containing the definition, or in the dynamic assistant (if you type the symbol). PS: Optimization "symbolic" immediately evaluates the rhs of the definition, while "numeric" assigns the definition verbatim, thus delaying the evaluation to the actual use of the symbol for displaying results. I find this slightly odd but there is only one guy to change or explain that... Edited by user 01 November 2013 01:21:55(UTC)

Moreover, using the symbolic evaluation, you cand reach the target defining the parametric variable before the parameters Davide Carpi attached the following image(s): |

Thank you both mkraska and w3b5urf3r_reloaded.
I have used w3b5urf3r_reloaded's solution before, but did not think of it this time because I wanted a different flow to the work.
I did not even know about right clicking an equation as mkraska suggested, so that will help me also.
