The collocation method is one of expansion methods which is used to approximate the linear and non-linear integral equations. This method can be used with basis functions such as standard polynomials {1,x,x^2,x^3,...}, Taylor polynomials, Chebyshev polynomials (first, second, third and fourth kinds) and others. What are the orders of convergence of collocation method with standard polynomials and Chebyshev polynomials ( second, third and fourth kinds)?
