Angle between two points with x and y coordinatesAngle in between two points with x , y coordinates Last edited by model (20110811 15:35:00) Maths is Doctor that make our life easy .. https://www.facebook.com/groups/Maths.GIS/ #2 20110811 17:37:10
Re: Angle between two points with x and y coordinateshi model I thought you wanted (v) The function atan will return the 'principle value' ; most likely this will be an angle between 90 and +90. If you want to get a positive angle for any coordinates, you'll need to test the sign of the answer rather than worry about the size of the angle. (vi) I do not understand the output "move to right/left side" means. Please explain what you are trying to achieve here. (vii) You have an angle of 171 for these coordinates. I make it 10.9 degrees. Are we talking about the same thing? Please post again, Bob Last edited by bob bundy (20110811 18:23:22) You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #3 20110817 18:06:24

Re: Angle between two points with x and y coordinatesWell @Bob , I changed my condition regarding angle direction to eat side or west side . Last edited by model (20110817 18:33:57) Maths is Doctor that make our life easy .. https://www.facebook.com/groups/Maths.GIS/ #5 20110817 18:45:08

Re: Angle between two points with x and y coordinatesHi model;
Isn't that two points?
What are you asking here is for the angle between two line segments that are determined by 4 points. Is this correct? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #10 20110818 04:52:28
