Hello,
I have a problem I've been trying to solve. I originally have vector AB. I know both vector A, vector B, and the angle between. They are on the same plane.
Now say I change the angle between the two vectors. They still remain the same magnitudes, and remain on the same plane. Assume vector A is fixed. How can I find the new updated vector B.
My attempt at a solution:
|A||B|cos theta = A*B
A, |B|, and theta are known
Equation 1)
|A||B|cos theta = axbx + ayby + azbz
Equation 2)
ax + by + cz = d
This is the equation of the plane that the vectors are located on.
My problem is I need one more equation to solve this. Maybe I am going about this the wrong way? Any help is appreciated.
Thanks,
AS
