 Author Comment/Response Fred 11/27/08 11:53am Hello, Let's consider the following example: ************************************** NumValues={ a->2, L->50 }; y[x_]:=a*Sin[x/L*Pi]; Plot[y[x]/.NumValues,{x,0,L}] ************************************** It won't work, because L in {x,xmin,xmax} is not evaluated. The only solution I've found is: ************************************** Plot[y[x]/.NumValues,{x,0,L/.NumValues}] ************************************** ...but it's not very practical when /.NumValues has to be redundant. Better would be something like : ************************************** Plot[y[x],{x,0,L}]/.NumValues ************************************** ...but it doesn't work! Another problem with the same function y: ************************************** Manipulate[y[x],{a,0,5}] ************************************** It doesn't work : y[x] is displayed as defined, but a isn't evaluated as I move the slider. And again I don't want to define y as a function of x AND a AND L, because in reality I have many "constants" (a, L, ...), the effect of which I want to see only sometimes. Are there any solutions to these problems? Thank you! URL: ,
