Gen Nav questions

Hi

there are a few questions that are confusing me right now with regards to gen nav.

these are departure and convergency. I never seem know which formula to use and when. I understand the 2 formulas. Ch long x sine mean lat and ch long cosine lat. can someone give an example of when I should use both of these.

Right now I'm looking at q' 5566 in the atpl online system.
Given: Position 'A' N60 W020, Position 'B' N60 W021, Position 'C' N59 W020. What are, respectively, the distances from A to B and from A to C?

Why do I use the departure one for this question and not the convergency?

This is probably a pretty stupid question but its totally confusing me.

Thanks in advance
