Thanks for the formula, but I still do not get the correct bearing angle. It seems to me it is usually simpler to insert a function to convert Lat/Lon to UTM coordinates (where all values are positive long integers) and work with meters on a projected plane rather than decimal degrees...
What is sin 2x double angle? The double angle formula is used to calculate sin 2x, cos 2x, tan 2x, for any given angle 'x'. The sine double angle formula for an angle 'x' is sin 2x = 2sin(x)cos(x).What is the Double Angle Formula? The double angle formula can find the valu...
