Problem 3 Given m data points ($1,y1),($2,y2),...,($m,ym). We want to t an exponential function y = c0 - cc\" to these data points. When we plug in the data points to the functions we want to t, we obtain a system of non-linear equations with variables on, c1 (so we cannot use least squares method). The goal of this problem is to use some trick to make the least squares method applicable. a/ Perform necessary transformation (hint: taking ln) to change this into a least square problem A2: = b. b/ Derive the formula for the least squares solution (60, 6:1)
