Hi all,
could you please tell me how to count polar angle of a point with respect to another one using cross product?
I know that polar angle of a point [itex]p_0[/itex] with respect to point [itex]p_1[/itex] is the angle of vector [itex]p_1 - p_0[/itex].
For example, polar angle of (3,3) with respect to (2,4) is the angle of (1,-1) which is 315 degrees or [itex]\frac{7 \pi}{4}[/itex] radians.
How to count it using cross product?
Thank you.
