Does the following series converge(absolutely or conditionally) or diverge?

E= (-1)^(n)sin (1/n)/(ln(1+n))^(2)

can anyone help me solve this or atleast tell me which series test to use?

thank u

Hint: Note that sin(n-1) < n-1.
 
so do i jus use the p-test

don't i have to use the integral test making u=ln (n+1) ?
 
Rather than asking us what you should do at each step, why don't you try something and show us what you get? Post you working if you get stuck and then we can help you.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
