are you sure x1 is a plane?
i think it's a equation of a line since it's having only one parameter
Hey,
I do not understand whats happening here...
I have two planes in vector form, x1 = (3,2,-1)t and x2 = (1,0,1) + (1,1,1)s + (3,2,-1)t. I know they are parallel because the (3,2,-1)t part is the same. When trying to find the normal using cross product do i use the vectors (3,2,-1)t and (1,1,1)s ? Thanks.
