Suppose you have a function f(x)=cos(x) and two nodes 0 and π2 . 1) Find the interpolation polynomial of the given function and nodes using the Vandermonde matrix method. 2) Roughly hand-draw a comparison graph between f(x) and the interpolating polynomial. 3) Compute the actual interpolation error at x=0 .
