    Course- 0d ("over the top")

    Distance- 3600 nm

    Distance formuala-

    60 x (90- sin-1(sin(58d 45min) x sin(61d 15min) + cos(58d 45min) x cos(61d 15min) x cos(180d))

    Course formula-

    tan-1(sin(180) / (cos(61d 15min) x tan(58d 45min) - (sin(61d 15min) x cos(180))

    Time to figure this out- 5 minutes

    Sam L.
