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:
So, for the above example, it's the same as ?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...
