Hello,

Thank you for replay. This piecewise(0 > x(t) and x(t) > 1, 0, x(t) > 1, 1) makes sure that 0<=x(t)<=1 and x(t) is nonnegative. But since Maple consider it 0 otherwise I am having negative values for x(t). 

Thank you

Thank you for your replay. Now p1 added to local no more warnings but still no plot showed up.

This is the new warning:

Warning, cannot evaluate the solution past the initial point, problem may be complex, initially singular or improperly set up

I attached Maple file:

Thank you

This is great. I see now the clear idea. Thank you so much.

Hello,

This is the situation:

1-   I have an ordinary differential equation that I solved it and plot it.

2-   I define a random variable in the same ode then solve it randomly for example 10 times so I have 10 different solutions.

3-   From the 10 solutions I took the max and min of values at each time t.

4-   Now I need to plot the solution for ode in part 1 together with max and min from part 3. I suppose to get 2 lines one represent the solution for ode in part one and second is represent the random solution for ode.

Part 1 to 3 ok. But I have problem with part # 4 to plot the max and min values that I get. How can I plot the max and min values as a line that represents a random solution for the ode? 

Thank you
