I'm really confused on which angle here is "the angle at Ox", and how you find out.

That's a quick image I made of it. I have that as the vector but I'm not sure whether the angle is or or or .

That's the problem =\ , the only information given is:

Quote:

Given that and find the magnitude of each of the following vectors and the angle each makes with Ox.

What about with this example: ?

I've been answering those ones as just

EDIT: The a and b referred to in the information given is not referring to the angles, I should have given them different variables... - Sep 20th 2009, 06:20 AMPlato
It appears to me as if your text material is not standard.

So you really need to read it closely to find these definitions.

I can give a standard approach. Consider the vector .

The angle associated with that vector is:
