Hi guys and girls
Can anyone tell me what the formula is to find the bearing between two known coordinates
Id like to know how to do this manually...
Cheers

Lets say we have two point A and B, then:
DX = (xB - xA)
DY = (yB - yA)
if DX>0 & DY>0 then:
Azimuth = ATAN(DX/DY),
but if DX > 0 & DY < 0 then:
Azimuth = 200-ATAN(DX/DY), where 200 is grads if your using grads or 180 degrees if you are using degrees, in general you should have in mind that the formula will be constructed according to the TAN which is tan(θ) = Opposite / Adjacent.

Does this help?
dX = X2 - X1
dY = Y2 - Y1
Azimuth = ATAN(dX/dY)
Distance = SQRT(dX*dX + dY*dY)
