Hello Patrick!

Thanks for the soln. However, I am little confused...the first line (-1<x<1) in your answer, is that a rephrasing of the original question ? The original states |n|<1 so I thought it should be -1<n<1???

Thanks!

You're right Safina. I got careless. It should be n at the top, not x!

Let me re-write and repost a solution...

Done. (I've changed the image in my original post above)
