[tex]\sum\frac{(-1)^{x}}{x*\sqrt{x}}[/tex]

How many terms must be added to get an esimate with an |error|<0.001?

2. Relevant equations

[tex]s_n+ \int f(x)dx \leq s \leq s_n+ \int f(x)dx[/tex]

3. The attempt at a solution

I having some problems trying to attempt this. To use this the function must be continuous which it is. Then it has to be positive and decreasing--this to me is the rub. The graph is symmertic at the horizontal asymptote x=0. So part of the graph is negative and increasing. I feel like I hit a brick wall. The only other thing I can think of is to rewrite the demoninator as x^(3/2), compare to a p-series and then find how many terms.
