Homework Statement
I have a vector A and B in spherical coordinates, and I need to find:
- part a) The vector component of B in the direction of A.
- part b) The vector component of B perpendicular to A
Homework Equations
dot product
cross product
The Attempt at a Solution
Alright at my first look I saw vector component and I thought of the cross product which yields a vector result, but then I realized that it in no way tells us anything about B in the direction of A. So then dot product came to mind but that yeilds a scaler result. So I am kind of stumped as to where to start.
My only idea for part a was to take (A dot B)/vector A which would yield a vector result.
and I had no idea what to do for part b.
