Re 7.0.1 under WinXP.
The code below works as expected:
z = DSolve[{x'[t] == -L x[t] + u, x@0 == c}, x, t]
Manipulate[
Plot[Evaluate[x@t /. %], {t, 0, 10}, PlotRange -> {0, 5 u/L}],
{c, 10, 20},
{u, 10, 15},
{L, 2, 4}]
However, when z (DSolve output) replaces % (in Plot), there's no plot. What
causes this?
Thanks.
