for example L:= 5*x(t) ^2 + 5*y(t)
Can you use Greek letters as variable names and can variable names contain subscripts?
Can you make an equation wrap so that it doesn't go off of the printable page?
Is there a way to define symbolic constants? Say, 'm1' to represent mass one. I mean, is there a way to let Mathcad know that even though it is a symbol it is a constant?
How to solve a system of n equations of n variables in Mathcad?
Does Mathcad have some sort of ode solver (I am familiar with ode45 in Matlab)?
Can it do animations (plots over time) ?

I put some information in the attached file, but basically:
1) You are asking for derivatives of function with respect to another function; However this is variational calculus, not differential calculus, and I don't think that is what you want, see the file for more.
2) Much of what you are asking is easily found in help
