Hi Everyone,
I'd like to define an equation and then Manipulate the input variables. This does not work if I've saved the expression as a variable before hand.
Manipulate[x^2, {x,-1,2}]
Works fine, but the next example just shows "x^2":
y = x^2;
Manipulate[y, {x,-1,2}]
Should I be defining y as a Function, or using the == operator instead? I want to make sure whatever I use will work with the Solve command later, in order to work with a system of other equations.
Thanks!
