2.1. Using the Taylor series expansion for cos(x), which is given by f(x) = cos(x) = 1-5 + determine the one-term, two-term and three-term approximations of f(xo+h), where xo = () and h = 0).1,0.2, ..., 1.0, and compare these with the exact solution. Generate a MATLAB script and sketch plots of the various Taylor series approximations and associated errors as function of the independent variable x
