How Many Terms Are Needed to Estimate This Alternating Series Within 0.01?

Click For Summary
To estimate the sum of the alternating series ∞Ʃ (-1)n/(ln(n+1)) from n=1 within 0.01, the remainder estimate for the integral test is essential. The relationship Rn = s - sn indicates that the error can be bounded by integrals from n to infinity. A key theorem for alternating series suggests that the error can be approximated by the first term not included in the sum. The discussion emphasizes the need for a clear understanding of these concepts to determine the number of terms required for the desired accuracy. Ultimately, applying the theorem for alternating series is crucial for solving this problem effectively.

Homework Statement



How many terms of the series

Ʃ (-1)n/(ln(n+1))
n=1
are needed in order to estimate the exact sum within .01

Homework Equations



I know that I need to use the remainder estimate for the integral test where Rn=s-sn

and that ∫ from (n+1) to ∞ of f(x)dx \leq Rn \leq ∫ from (n) to ∞ of f(x)dx



The Attempt at a Solution



I tried to take the integral but I don't know how, and I can't figure out another way to approach the problem

I don't think you want to use an integral.

Hint: Don't you have a theorem for alternating series (with certain hypotheses) that compares the error to the first term not included?
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
