Hi, I've posted another thread asking for general help on how to solve numerically with excel. Here is my specific situation if anybody is well versed with Mathematica programming. I'd appreciate any help. I've successfully created a FindRoot to solve eqn's for one set of data points...

My quandary... it's related to not being able to evaluate numerically (non-algebraic solutions) with Excel. My Mathematica programming is limited, but I've managed to use Findroot to solve it, but it requires me to manually put in 3#'s, hit enter, then copy paste results back to excel...
