In Response To 'Re: Dynamic updating of variables in Manipulate'
---------
Thanks Yehuda, but when I try to define a function with a Dsolve I get an error in Manipulate.
In a simplified example:
f[w_, t_] := DSolve[y'[x] == Cos[w *x - t], y, x]
Manipulate[Plot[{Sin[w *x - t], {Evaluate[y[x] /. f[w, t] /. C[1] -> {Range[-5, 0]}]}}, {x, -10, 10}], {t, 0, 5*2*Pi}, {{w , 1}, 0.1, 5}]
I get an error: DSolve::dsvar: "-9.99959 cannot be used as a variable"
I think that this is because Manipulate assigns a value to x (= -9.99959) BEFORE solving the DSolve.
Is there any workaround?
