Question

What does doing A x B (cross product) gives us in 3d plane ?​

Answer 1

Acc. to me

it give 3 rd axis

Suppose you have A line on x axis[x] and B line on y axis[y]

if you cross product it then it give perpendicular line C on 3rd axis[z] that is perpendicular to both x and y axis lines.

You See- i means X axis ,j means Y axis,k means Z axis

i*(cross)j=k

I Hope it help
