Re: Solving on mathematica



Hi Chris,

there is not enough information in your equations to distinguish Uz from 

   Cb. In your equation they appear always as Uz-Cb. Therefore, either 

your equations are wrong or you need to replace the 2 independent 

variables Uz and Cb by a single variable and reduce the number of 

equations to 3.

hope this helps, Daniel
