comment Using either the Direct or Limit Comparison Tests, determine if $\sum_{n=2}^{\infty}\frac{1}{n\sqrt{n^2-1}}$ is convergent or divergent.
OK, I see it now - there was one example like this in my notes that I overlooked.

Why $n^2$? I was taught to pick the most dominant term, which appears to be $n$.

The most dominant term appears to be $n$ though. $\sqrt{n^2}=n$.

I think I like tuple in this context too...

comment Determine if vectors are linearly independent
@AndréNicolas I'm only starting to learn about matrices now... this was taught in this method so I presume this is how I have to do it on the assignment.

comment How do I calculate one of the points in a vector?
Oh, ok... I see. This helps a lot then to remember how to solve for points. Thanks.

So $\vec{pq}+p=q$? How does that work by adding a vector and a point?
