comment Solving $L=\frac{3}{2} \sqrt{4 \pi ^2 A^2+W^2}-\frac{\sqrt{5 W \sqrt{4 \pi ^2 A^2+W^2}+6 \pi ^2 A^2+3 W^2}}{\sqrt{2}}+\frac{3 W}{2}$ for $W$
@I. J. Kennedy hehe, right! I had to shut down after 6 hours or so... talk about entropy!

comment How to write the following quadratic equation in general form?
This question appears to be off-topic because it is directly about an assignment and does not show any effort by the OP.

@chris lol - mine is plugged in, and still a-computing...

comment Find Root Iteration
But without some working code it will be very difficult to reproduce your problem properly.

comment Find Root Iteration
Can you also supply a sample S? Your code really should produce some viable output.

comment Find Root Iteration
As of now, your code does not run when pasted (missing /mismatched brackets?). You can also use additional code to make retracing your steps easier.

comment Strange behavior of function (memory leaks)
Can you perhaps pinpoint the problematic code somewhat more? Otherwise, this will remain a very localized question.

@m_goldberg Unlike my FullSimplify, which is still chugging away merrily.

comment Find Root Iteration
Just paste the Mathematica code here and format it as "Code Sample" (the editor has a button for that). Subscripts and fancy typesetting are best avoided for readability. If you have major problems, paste it anyway and someone will probably help you out with the formatting.

Well, there you go :P

Did you try a Simplify or FullSimplify? Some assumptions might help with those, too.

comment Find Root Iteration
You should definitely go a for a MWE then. Without any code, this will likely be closed. Also, having to make up sample code to fit your verbal explanations is not very attractive.

comment How can I calculate matrix differentiation?
This site is about the software Mathematica. Since you do not mention it, I gues you want to post on math.stackexchange.com?

comment How to set the boundary fixed and apply the Young's modulus in Mathematica's FEM?
While the topic is interesting, I would suggest that you start with simpler example (e.g. a simple plate or even a beam) to see how that works out, and ratchet up the complexity later on.

Posting some code would be very useful, if only to save us time making up bogus data.

Please have a look at Table, possibly together with FindRoot or Solve.
