To find the value of Cos(π/6), we can use Lagrange's Interpolation Formula. The formula is as follows:

f(x) = Σ(yi * li(x))

where, f(x) = interpolated value of the function at x yi = value of the function at the ith point li(x) = Lagrange's coefficient polynomial

We need to find the value of Cos(π/6), which means we need to interpolate the function y = Cos _________ _________ ________ ________ _______ _____ _____ __________ ______ ________.
