AMTH 16C TEST 3 Spring 2002 1.( 18 pts) Assume that X n =1 a n is a convergent series , and X n =1 b n is a divergent series. Let X n =1 c n be a series with partial sums S k . Indicate the convergence or divergence of X n =1 c n by putting C for convergence , D for divergence and N for no conclusion can be made in the blank space provided for each part. i) 0 < c n < b n .............. ii) 0 < c n < a n .............. iii) 0 < a n < c n .............. iv) 0 < b n < c n .............. v) lim n →∞ S n = 5 .............. vi) lim n →∞ S n = .............. vii) lim n →∞ c n = 0 .............. viii) lim n →∞ c n = 1 .............. ix) lim n →∞ c n = 1 2 .............. x) lim n →∞ c n = 2 .............. xi) lim n →∞ c n +1 c n = 1 2 .............. xii) lim n →∞ c n +1 c n = 0 .............. xiii) lim n →∞ c n +1 c n = 2 .............. xiv) lim n →∞ c n +1 c n = 1 .............. xv) lim n →∞ a n c n = 2 .............. xvi) lim n →∞ a n c n = 0 .............. xvii) lim n →∞ b n c n = 2 .............. xviii) lim n →∞ c n b n = 0 .............. 2.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
