Summary of contents: The problems in this workbook can be solved using the same basic mathematical techniques as used in the Workbook on Economic Applications 1 but the problems are generally harder. These techniques include solving linear and non-linear equations, and sets of linear and non-linear equations containing up to three variables. No calculus is used. The functions used include polynomial ( to degree 3) , rational, algebraic and exponential. There are 21 problems. 35 pages.
