I am using FindRoot to solve a system of nonlinear algebraic
equations. The number of equations and variables depends upon a
number input at the beginning of the notebook. Since the equations
are specified to FindRoot in a single list, there is no problem adding
more equations to the system - just append them to the initial list of
equations. However, I am not clear on how one adds new variables that
FindRoot is to solve for. This is because they must each be given as
separate arguments. For context:


As you can see, I may not simply build a list of variables dynamically
and hand it to FindRoot because a list is a _single_ entity or
argument. FindRoot requires a sequence of arguments (multiple
entities) to specify the variables.

Ideally I would like a way to have a list be interpreted as a sequence
of arguments - but I have found no clear way to do this in the book
and I am wondering if it may not be possible.

Does anyone have a way to do this kind of thing? Or am I just being
foolish and there are better ways to specify the problem and solution
in Mathematica?

Thanks in advance,
Guy Delamarter
