• Describe relative angles between points (like driving directions)

  - by aan234g

  I have a list of points with x, y coordinates. I know how to get the distance between points with sqrt(pow($x2 - $x1, 2) + pow($y2 - $y1, 2)) and the angle between points with atan2(y1 - y2, x1 - x2). How can I calculate the relative angle between the points (left, right, straight)? So, if I'm at point 1, what is the relative direction to point 2, then 2 to 3, 3 to 4, etc... Thanks for any help!

• how to get powershell to look for files in other folders when moving items?

  - by steeluser

  I have written this script to move files to the destination folder. Looks like I am missing something here because when I run the script, it is only looking for .zqx files in current directory and not all the drives. Please note that the ( dir $paths..) part is returning the list of .zqx files promptly. Paths.txt has drive letters like this C:\ D:\ E:\ $paths = get-content paths.txt mv (dir $paths -r -fi *.zqx | ?{$_.lastwritetime -lt ($sevendaysold)}) -dest e:\xqz Thanks Steeluser
