Finding a Taylor Polynomial to Approximate a Function Ex. Polynomial Approximation, Interpolation, and Orthogonal Polynomials • • • In the last chapter we saw that the eigen-equation for a matrix was a polynomial whose roots were the eigenvalues of the matrix. However, polynomials play a much larger role in numerical analysis than providing just eigenvalues., TAYLOR POLYNOMIALS AND TAYLOR SERIES The following notes are based in part on material developed by Dr. Ken Bube of the University of Washington Department of Mathematics in the Spring, 2005. 1 Taylor Polynomials The tangent line to the graph of y = f(x) at the point x = a is the line going through the point ()a, f (a) that has slope f '(a).
