I've encountered a problem while trying to use the answer from a NDSolve in two separate plot commands. To illustrate the problem, I'll use a simple differential equation and only one plot command. If I write something like this:
{Plot[x[t], {t, 0, 10...

So in the expression you posted,
Plot[x[t], {t, 0, 10}]
just goes ahead and evaluates... .
Your problem is that Plot[] does some funny things to make plotting more convenient, and one of the things it does is just not plot things it can't evaluate numerically .

Hi,
The following is the differential equation for a beam on a varying-stiffness elastic foundation. Does anybody know how to solve such an equation as a closed form solution (if possible)?
E*I*y(x)''''+k*y(x)/x^3=0
where k is a constant.
Answer Snippets (Read the full thread at eng-tips):
Should.
If the solution to that equation is all you need, it's easy to find a series expansion for it.
However I do not think your differential equation comes close to applying to the problem you.
Above.

Hello
i write the equation of a linear circuit with D operator
such as before i change D to dv/dt and 1/d to integral and then differentiate it.but in this equation how can i obtain the differential equation?
