My concern is on LK, Why using the formula for longitude instead of latitude, , , , 2πRcosx

[SerahPenjemali]

Sir, I'm really confused, why do we add, and why do we multiply????

[musonda]

Sir are we not supposed to put the units for question b Answer

[lumunochisumpa]

Isn’t it 30 degrees since places located in the same side eg west must be subtracted

[mapsuni-verse]
