### Class Details [line 21] Given n points (x0,y0)...(xn-1,yn-1), the following methid computes the polynomial factors of the n-1't degree polynomial passing through the n points. Example: Passing in three points (2,3) (1,4) and (3,7) will produce the results [2.5, -8.5, 10] which means that the points are on the curve y = 2.5x² - 8.5x + 10. #### Tags:
