To Solve for Final Position:
If given P1 and a course and distance, work backward through the equations to find what you need.
Use sin C = p/D to solve for the displacement (p), then solve for l using tan C = p/l. p
can then be converted into DLo using p = DLo cos L2. As you know the initial
L1 and l1,
simply add or subtract l and DLo to find L2 and l2.

Cn = 234.69° T
C = S 54.69° W

D = 398nm



DLo = 376' (W) = 6°16‘ (W)
