Sp 99 EGN 3420 EXAM I Name________________________ SHOW ALL WORK! Problem 1 (25 pts) Given the function f x e x x ( ) sin = - , a) Find f 2 ( x ), the second order truncated Taylor Series Expansion of the function about the point x 0 . Leave your answer in terms of x and x 0 . Note: Your final answer should not be f x f x f x x x f x x x 2 0 0 0 0 2 2 ( ) ( ) ( )( ) ( ) ( ) = + - + ′′ - b) If x 0 = π /2, then the quadratic function f 2 ( x ) can be expressed as f x a a x a x 2 0 1 2 2 ( ) = + + where a a a 0 1 2 , , and are constants. Find a a a 0 1 2 , , and and leave your answers in terms of π .
