1. If we keep the center a=0 , what is the least amount of error that is generated between P(4) and cos(4) ?

2. Within this application, is there a "best" way to approximate cos?(4)? Explain.

N = 8 8 X= 4 P(ac) = Ck(x - 0 )k 3 k=1 Error 0.25682 = 0 2 - (a, f (a)) -6 -5 -4 -3 -2 -1 0 1 2 (4, P(4) 5 6 4, f (4) ) -1
