Consider the improper integral I = f dr. In order to determine if I is convergent I 3 or divergent, we need to split I into a sum of a certain number n of improper integrals that can be computed directly (i.e. with one limit). What is the smallest possible value for n? (A) 2 (B) 3 (C) 4 (D) 5 (E) 6 5. Which of the following sequences converge? n! n² an = √n² bn = Cn = (-1)n + n³-1 2n n³ 1 (A) (an) and (cn) (B) (an) and (bn) (C) (an) only (D) (b) only (E) (cn) only 6. Consider the following series n (n² + 2)³* n=1 Among the four tests • Integral Test . Comparison Test • Limit Comparison Test . Ratio Test which can be used to prove this series is convergent? (A) All but the Integral Test (B) All but the Comparison Test (C) All but the Limit Comparison Test. (D) All but the Ratio Test. (E) All of them.
