Hey. I'm currently learning about vectors and i have come to a point where I am just plain stuck. This may be a stupid question but i don't get it.
Now say u have 2 vectors and u need to get there components (the vectors are A and B)
so u have
Ax = A cos theta
Bx = A cos thetax
Ay = A sin theta
By = A sin thetax
assuming that neither have any negative components What i don't understand is if there is a vector in 3-d space how do u get Az and Bz
i mean even if u were working in x-y plane but finding the product of A x B
the formulas for C Components are
Cx = AyBz - AzBy
Cy = AzBx - AxBz
Cz = AxBy - AyBx
and u need that Z-component for both A and B
I would appreciate any help u could give me.
Thanks in advance.
