MA 126 Midterm: MA_126_test3 Fall 2015
Document Summary
Closed book - calculators and one index card are allowed! Clearly write your answer (only) in the space provided after each question. Very limited partial credit or none at all for this part of the test! Determine whether the sequence an = ln(3n + 2) ln(n) is convergent or divergent. Find its (exact) numerical value if it converges! 24 n(n + 1) is convergent or divergent. Xn=1 ( 1)n n + 1 n n is divergent, absolutely convergent, or conditionally convergent. (be speci c here!) You must show your work on this part of the test to get full credit. Displaying only the nal answer (even if correct) without the relevant steps will not get full credit - no credit for unsubstantiated answers! Find the radius and interval of convergence of the power series. Be sure to check any endpoints that exist!
