EGN 3420 EXAM I Name________________ Sp 94 SHOW ALL WORK! Problem 1 Consider the function f(x) = x 5 - 1. A) Find an expression for the difference f(x 1 ) - f 2 (x 1 ) where f 2 (x) is the second order truncated Taylor Series expansion of f(x) about some point x 0 . Leave your answer in terms of x 0 and x 1 . B) Evaluate the expression from Part A) when x 0 =1 and x 1 =1.1
