help

a student (or teacher) types a function in like this: 3*x^2 - 4*x + 2. The program can produce a variety of results: the derivative, the integral, the roots, the etc. There should be a variety of standard formulas available, stored in a file and the user can select the formula they want, then type in the exact numbers (e.g. coefficients). It should be possible to store a set of results (reports) for later use (e.g. Printing). Buy using static array and non gui. How would i start this program out
