ADVANCED CALCULUS I, DR. BLOCK, SAMPLE MIDTERM, FALL 2011 PART ONE: COMPLETE THE DEFINITIONS (4 points each, 20 total points) 1. Suppose that S is a subset of the set of real numbers, and w is a real number. We say that w is an accumulation point of S if and only if 2. Suppose that f : D R , where D is a subset of R . Suppose that a is an accumulation point of D ( -∞ ,a ) . We say that lim x a - f ( x ) = if and only if 3. A sequence { a n } diverges to -∞ if and only if 4. A sequence { b n } n = i is a subsequence of the sequence { a n } n = j if and only if 5. Let { a n } be a sequence. Then lim sup n →∞ a n is PART TWO: PROOFS (1 proof, 8 total points) 5. Prove that any convergent sequence is bounded. 5 (alternate). Prove that any two limits of a convergent sequence are the same. 5 (alternate). Prove that any bounded, increasing sequence converges.

Unformatted text preview: 6. Determine whether the given sequence converges or diverges. If the sequence converges, nd the limit. If the sequence diverges, determine whether the sequence diverges to ,- , or neither. Justify your answer. a n = (sin n )( n 5 n 4 + 2 n ) n 7. Evaluate the given limit if possible. Justify your answer. lim x + ( (exp( 1 x ))( x 3 + x-1) ) 8. Evaluate the given limit if possible. Justify your answer. lim x ( x sin x ) 2 3 x 4 + 2 x + 5 PART FOUR: DETERMINE IF THE STATEMENT IS TRUE OR FALSE. (2 points each, 4 total points). 10. If S is the set of rational numbers with 1 &lt; x &lt; 2, then 2 is an accumulation point of S . 11. Every sequence of real numbers has at least one subsequence which coverges to a real number....
