how do you get the other numbers

jdoe0001 · Answer

sorry I'm a bit lagged :/

jdoe0001 · Answer

anyhow, you don't, those are just repetition/sequence notations

0.71 + 2pi on the Unit Circle on one cycle
0.71 + 6.28 + 6.28  on second cycle
0.71 + 6.28 + 6.28 +6.28 on third cycle
0.71 + 6.28(N) on Nth cycle

where N is an integer greater than 0

$2\pi = 6.28\  radians $  thus :)
