Hi, I'm trying to find the equation of a path on a sphere sort of like this red curve between P and Q above.
I think this solution below can calculate this curve. My question is, what exactly does 'd' represent? Also does the 'f'
variable behave similar 't' in a parametric equation?
Any help will be much appreciated, thanks in advance
