I do not know the domain of the answer. However equations come from a real problem.

What is your suggestion?

Thank you


Yes, I am tring to get y-values for the curves at a common set of sigma values.

if it is not possible to get data for whole curves in the same time, how i can get them separately.





the general form is as follow:



I only want to simplify it more



How I can determine Time period by maple automaticly?


thank yoy.

I have a problem for attaching file.

Please see it agin.

@Carl Love 

Thank you for your help in this regard.


@Carl Love 

Thank you dear Carl,

Please see final program.


@Carl Love 

Thank you.

You say correct. I tayped equatio but there is a problem for plotting?

Please see it,


@Carl Love 

Thank you.

assume that:


Also, we have not any differential refer to V(t), so initial conditions are not on V.

For now, we want plot Z versus  t.


@Carl Love 

Thank you. in this case V(t) = constant.

Initial cinditions are:

 Z(0)=0 and Z'(0)=0


@Carl Love Equations 17 and 18 are ode and equations 21 and 22 are boundary conditions.

@Rouben Rostamian  

I send a paper that propose a nontrivial solution.

Please see it.



@Rouben Rostamian  

Yes, you say correct.

Thank you.

@Rouben Rostamian  

Thank you..

but in some papers via Homotopy Method  nontrivial solution is proposed!

But from maple maybe this not possible.
