Department of Mathematics, University of Toronto Problem Set Supplement #2 MAT 137Y, 2008-09 Winter Session Not to be handed in. Assignment Posted/Revised: January 5, 2009, 14:55 While the following problems do not have to be handed in, you will be responsible for this material for the second term test. 1. Consider the function f ( x ) = x 3 - x + 1. (a) Show that f ( x ) has exactly one root c , and that c ( - 2 , - 1 ) . (b) Using a calculator, apply Newton’s Method several times until the last five decimal places remain the same after iteration – show your work. Round off to get a 4 decimal place approximation d for c . (c) By evaluating f ( d ± 1 2 · 10 - 4 ) , show that
