Unformatted text preview: Math 508 Exam 2 Jerry L. Kazdan December 9, 2010 9:00 10:20 Directions This exam has three parts, Part A asks for 3 examples (5 points each, so 15 points). Part B has 4 shorter problems (8 points each so 32 points). Part C has 4 traditional problems (15 points each so 60 points). Total is 107 points. Closed book, no calculators or computers but you may use one 3 00 5 00 card with notes on both sides. Part A: Examples (3 examples, 5 points each so 15 points). Give an example having the specified property. 1. A function f C 1 ([ 1 , 1]) but is not in C 2 ([ 1 , 1]). 2. A bounded sequence a k in a complete metric space M where a k has no convergent subsequence. 3. A sequence of continuous functions f n ( x ) C ([0 , 1]) that converges pointwise to zero but R 1 f n ( x ) dx 1. [A clear sketch is adequate.] Part B: Short Problems (4 problems, 8 points each so 32 points) B1. Let f ( x ) be a smooth function with the properties: f ( 1) = 1, f (0) = 0, and f (1) = 1.(1) = 1....
