Dear Colleagues, Manipulate[Plot[\[ExponentialE]^(k t), {t, 0, 1}], {k, -1, 1}] works fine. However, if I solve the corresponding ODE symbolically: ds = DSolve[{x'[t] == k x[t], x[0] == 1}, x[t], t][[1]] it does not work: Manipulate[Plot[Evaluate[x[t] /. ds], {t, 0, 1}], {k, -1, 1}] Could anyone help me please? Thank you, Janos
