Confused about Vector direction

Click For Summary
SUMMARY

The discussion clarifies the terminology used in vector direction, specifically the phrases "north of east" and "east of north." "North of east" indicates a rotation of 20 degrees counter-clockwise from the east axis, while "east of north" signifies a 20-degree clockwise rotation from the north axis. This distinction is crucial for accurately interpreting vector orientations in physics and engineering contexts.

Hello everybody! First time poster here. Anyway, as the topic stated I'm confused about the naming of vector direction. For example, the difference between north of east and east of north?

20 degrees "North of east" means "20 degrees north of the east axis. Specifically: you start with the east axis (just like the positive x axis) and rotate counter-clockwise for 20 degrees.

20 degrees "east of north" means you start with the north axis (or Y axis) and rotate clockwise 20 degrees.
