AI Thread Summary
The discussion revolves around calculating bearings and distances between two points defined by Eastings and Northings. The user successfully calculated the bearings for point A and point Y using trigonometric functions, resulting in values of 37'29'32' and 45', respectively. They are unsure if they can simply add these bearings to find the bearing from A to B, suggesting a need for clarification on the correct approach. A suggestion was made to draw the points on graph paper for visual verification, but the user emphasizes the need for a numerical method suitable for exams. The conversation highlights the importance of understanding bearing calculations in navigation and geometry.

Homework Statement


Hi everyone. My problem is related to bearings, and finding the bearings between two points and their distance apart.
A= Easting 182.373, Northing 139.901
Y= Easting 200 Northing 200

Homework Equations



The Attempt at a Solution


Now for A's bearing I used pythagoras and inverse tan to calc the angle from the East/x axis was 52'30'28', thus subtracting it from 90 degrees gave me 37'29'32' from the y axis/north to bearing A.

For bearing B i did the same, and came up with a value from it's north position clockwise to Y bearing of 45' (inverse tan (200/200)).

Now to find the bearing from A to B, do I just add these bearings together, for a A to Y bearing of 82'29'32'?

If not, what do I do. Surprisingly google couldn't help me.

Thanks a lot

You could draw this out on a sheet of graph paper, using an appropriate scale, then measure the angle and distance apart of the two locations to see how well your calculator work compares with the "reality".

Thanks mate but I kind of need how to do it numerically to do it in exams...
