In this exercise you will familiarize yourself with recursion in C by determining coefficients of Chebyshev polynomials.
Recursion is a common method used to solve many computer science and mathematics problems.
In this lab you will explore how C allows you to perform recursion and how you can use arrays in recursion. The approximation functions are important in simplifying data and mathematical expressions. Linear least square fitting is a very common method. Another different technique involves approximating functions by linear combinations of polynomials. Other interesting properties are beyond the scope of this project.
