About this worksheet:
This worksheet explains the elements of variables and their role in PTC Mathcad software. Specifically, this worksheet teaches you how to undefine a variable using two simple methods. A variable that has been defined numerically may have to be undefined symbolically before it can be used as the variable to be solved for in an expression. This worksheet provides you with a step by step example for how to do so. The returned results do not replace the originally defined numerical value.
