Write function (len) - arclength (x,y) which takes as input the points which were output by ellipse and computes the approximate circumference as a sum Copp(a,b) = (xi+1 *;)2 + (Yi+1 - y.)2 Check that Capp(aa) is close to the expected circular circumference for values of a in {1,0.8,...,0.2) by comparing the difference between your app (using = 100 points in each case) and the true circumference 27ta. In general does Capp tend to be an over-estimate, an under-estimate, or neither? Can you explain why?
