A Basic Vector Question

[From: ] [author: ] [Date: 11-05-10] [Hit: ]
Solve for theta and that is your angle (in radians).P.S.,......
I have to find the angle between a resultant vector and the z axis. What is the approach for doing this?
Should I use the dot product or the cross product formula?

Thank you for your time.
=)

Dot Product.

A . B = ||A|| ||B|| cos (theta). Solve for theta and that is your angle (in radians).

P.S., z axis = <0,0,1>
