Sp 95 Exam 1A Name __________________ EGN 3420 SHOW ALL WORK! Problem 1 (25 pts) Consider the function f(x) = x 10 - 1. A) Find an expression for the 2nd order truncated Taylor Series Expansion f 2 (x) evaluated at x=1.01x 0 , where x 0 is the point at which the series is expanded about. Leave your simplified answer in terms of x 0 . Numeric constants should be rounded to 5 places after the decimal point. B) If x 0 =1, find the true relative error, as a per cent, in f 2 (1.01x 0 ). C) If x 0 =1, find f 3 (1.01x 0 ). In Parts B) and C) express your answer rounded to 5 places after the decimal point.
