Excuse me for my unclear question title, math terms have never been my forté. However being new here and knowing I shall be staying here for a while, I thought it's best to do things right with the community and site.
I just asked my first question here and got a great response and nice welcome. However I have no idea which answer I, as a community member should pick.
The reason being is that the first one explains how to get there (which is something I requested in the question itself) whilst the other one is the actual answer to the questions but doesn't directly tell me how he got there even though he did somewhat clarify that in the comments.
A general rule of thumb for such scenarios would be greatly appreciated!
