S = arc length
h = height at highest point
a and b = angles like the angles of a canon when calculating trajectory.
This has to do with an idea of a method FTL travel for a story I want to write. It goes along the lines of the shortest distance between two points is a straight line. since space is curved - that curve being s - then it would be better to go along c.
btw sorry for my misspellings
Thanks again
