... Consider a box with sides AX, AY, and AZ meters long. The vector A can be defined as A = (AX i + AY j + AZ k) m The projection of the vector A in the x-y plane is A´. The magnitude of this projection, A´, is found by using the same approach as a 2-D vector: A´ = (AX2 + AY2)1/2 . The magnitude of the ...
