Problem 3 : Polynomial evaluation by nested form & by formula The purpose of this exercise is to practice with creating for loops, applying nested multiplication, and defining function.m files. Create a function in a separate .m file with the following definition: function [p] = nestedPoly(x, coeff) that returns the value of the polynomial with coefficients coeff on x using nested multiplication. The coefficients should be assumed to be stored from higher to lower order. You may use the function posted on Canvas. In your prob3(), 1 (a) Call your function to evaluate the polynomial P(x) = x30 + x29 + x28 + ... + x2 + x + 1 at x You may find the function ones useful for creating the vector of coefficients of P. (b) Notice that the sum you calculate on the previous step is a sum of a geometric sequence with ratio x. Therefore, another way to evaluate P(x) on any point x, x + 1, is to use the formula P(x) X31 - 1 X-1 Use this formula to evaluate P and compare to the result you got using your nestedPoly function, using the absolute error.
