24. (1 point) For the following alternating series, n = 1 a n = 1 - 1 10 + 1 100 - 1 1000 + ... how many terms do you have to go for your approximation (your partial sum) to be within 0.001 from the convergent value of that series? Answer(s) submitted: (incorrect) Correct Answers: 3 25. (1 point) For each of the following series, tell whether or not you can apply the 3-condition test (i.e. the alternating series test). If you can apply this test, enter D if the series diverges, or C if the series converges. If you can’t apply this test (even if you know how the series behaves by some other test), enter N. 1. n = 1 ( - 1 ) n e n n ! 2. n = 1 ( - 1 ) n n ! n n 3. n = 1 ( - 1 ) n n ! e n 4. n = 1 ( - 1 ) n n 2 + 5 5. n = 1 ( - 1 ) n n n n ! 6. n = 1 ( - 1 ) n cos ( n π ) n 5 Answer(s) submitted: (incorrect) Correct Answers: C C N C N N Generated by c WeBWorK, , Mathematical Association of America 9

    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.
