In order to implement complicated nonlinear functions in a computer, so- metimes polynomial approximations are used. in this exercise, we explore one way of computing these using linear programming. consider a scalar function f(x), which we are trying to approximate over the interval [a; b] with a polynomial p(x) of degree d. as a measure of how well the polynomial approximates the function, we can use the norm. || f – p||. : = sup if(x) – p(x)]. the minimax or chebyshev polynomial approximation of degree d of f(x) is then defined as min || f (x) – p(x) ||, where pa is the set of polynomials of degree less than or equal to d. because the true il . il norm can sometimes be troublesome to compute, throughout this exercise we will use instead a discrete approximation given by: ||g|| : = max g(xi)], where the ti is a set of n points equispaced on the interval. give a standard linear programming formulation of the chebyshev approximation problem in the || . ii norm.

Answer asap ! the shortest path from point a to point b goes through a pond. to avoid the pond, you must walk straight 34 meters along one edge of the pond, then take a 90 degree turn, and again walk straight 41 meters along another edge of the pond to reach point b. about how many meters would be saved if it were possible to walk through the pond? a. 11 m b. 20 m c. 30.45 m d. 21.73 m
