comment Solve $\operatorname{Arg} (z-2) - \operatorname{Arg} (z+2) = \frac{\pi}{6}$
Surely this only gives one of an infinite number of answers?

comment Stopping times, Filtration, Martingales,
The system works a lot better if you only ask one question per question. And if you want to get useful answers then it's helpful if you can indicate what you've tried and why it didn't work.

comment Can a basis have dimension less than the space that spans?
The title is misleading (or indicates that you are misunderstanding the situation). S is a one-dimensional space, so the basis in fact has the same dimension.
