Webthe Newton form of the interpolating polynomial Often we have data collected from some difﬁcult function f(x). With interpolation we can represent the data by a polynomial. Input: (xi;fi = f(xi)), i = 0;1;:::;n, n +1 data points, xi 6= xj, for all i 6= j, distinct values for x. Output: p(x) a polynomial of degree at most n so that WebImportant: Beginning with Excel version 2005, Excel adjusted the way it calculates the R 2 value for linear trendlines on charts where the trendline intercept is set to zero (0). This adjustment corrects calculations that yielded incorrect R 2 values and aligns the R 2 calculation with the LINEST function. As a result, you may see different R 2 values …
