hi does any one have notes, or how to do spherical geometry? im very confused on the N,E,S,W thing.. and also the time.. how they give u a co-ordinate and ask you wat time it is at another co-ordinate.. thanks eg. (53`S,142E) is 7:21am what time it wud b in 32N,42E.. etc

hmm well.. for every degree its.. 4 minutes i think. or 4 degrees equals 1 minute lol. argh sorry.. let me get my book

yep 1 degree equals 4 minutes.. so...let me see if i can get this right.

142-42 equals 100 degrees.
4 x 100 = 400.. 400 minutes.. 4 hours and 40 minutes :S and then ud add that to the time or take away depending on where it is.. do u get me? i dont think im making sense. grr..
