Hi,

Here is the simplified version of the three equations I am trying to find three unknowns with.

My first problem is the syntax of the FindRoot command- I used

FindRoot[{eqn1==0,eqn2==0,eqn3==0},{{k2,k2guess},{k3,k3guess},{c3,c3guess}}]

but it tells me that the function value is not a list of numbers with dimension 3... where did I go wrong? Surely the program has a clearer way of informing me that this problem has no solution?

I am reasonably sure that these equations actually have no solution until I tweak the constants, but I am just trying to get a method to solve them so that I can try different constants and see if ANYTHING could work.

Thanks!
Kaitlin
