1. The problem statement, all variables and given/known data How can I evaluate function in some point of x? So, user inputs function in a character string, and he inputs the value of x. The program then needs to evaluate f(x). I have read something like this:http://faculty.cs.niu.edu/~hutchins/csci230/arith.htm [Broken] But, I'd like to see how it looks some routine/module for this... 2. Relevant equations 3. The attempt at a solution Unfortunatley didn't try anything because I don't know where to start and how to solve my problem.
