pagi mass/mba :-) saya bingung ni soal trigonometri/matematika.
saya buat sistem perhitungan jarak 2point seperti http://www.movable-type.co.uk/
pakai rumus haversin/Spherical Law of Cosines, di sitem perhitunganya sudah benar cuman perhitungan manualnya saya kacau, jauh banget dari perhitungan drsistem, nyari contohnya mbah google nda ngasih. kira" mass/mba ada yg bisa bantu untuk contoh soal+jawaban+jalanya perhitungannya??
klw salah group buat tanya ini, kira" kepada siapa saya harus bertanya :'(

klw mau coba ::
point 1 = -6.972318 (lat1) / 108.523505 (lon1)
ponti 2 = -6.92978 (lat2) / 108.49100 (lon2)
ini rumusnya :: ACOS(SIN(lat1)*SIN(lat2)+COS(lat1)*COS(lat2)*COS(lon2-lon1))*6371
atau bisa pake lokasi sendrir :-)
