Hi everyone，
I have a task to solve complex differential Equations: The problems are as the following picture:
It seems that these equations can be solved by Mathcad. Because, I can get any point's value. However, I can't plot it.
So, my problems are:
1) Why I can't plot? what should I do?
2) The left table, which shows the P10_j, seems very strange. Why the value is always [1, 1].
Please kindly find the attachment, which is my input file of this task.
Hope to get your help! Thank you very much!
Jason
>2) The left table, which shows the P10_j, seems very strange. Why the value is always [1, 1].
It is a nested area - a vector with matrix as elements.
See please the attach!
I've looked at this again and noticed that you only have two equations in ODE form, one of which you can solve analytically anyway!
You only need to solve for Pn using a numerical differential equation solver.
See attached.
This is what the output looks like:
