First, prove that the following series converges. Second, calculate the number of terms n that must be added in order to find the sum to within 0.001 and type your answer into the answer box. ∑ n = 1 ∞ ( − 1 ) n 4 n 2 {“version”:”1.1″,”math”:”\sum\limits_{n=1}^\infty (-1)^n \frac{4}{n^2}”}(Show all sufficient work in steps, use the technique or method discussed in this course and include the name of test you used.)
