Hi there,
I'm stuck on the above question (part b). The part i'm actually stuck on is adding vector components (I think this is what it's called)
ABCD is a rectangle. I have the coordinates of A (4, -2, 3), B (2, 0, -1) and C (5.5, 5.5, 0).
To find D i'm told by the markscheme that OD = OA + BC. What does this actually mean?
I don't have anything like this in the book i've been studying from so i've no idea how to complete the question.
Thank you for any help
