I'm working on an exercise, not sure if I am posting in the right place though... first time on this website
Vector A = 3i - 2j + k
Vector B = -2i + 5j + 4k
Vector C = -4i + j + -2k
Vector D = 2i - j + 4k
determine (alpha), (beta), and (gamma) such that Vector D = (alpha)VA + (beta)VB + (gamma)VC
I have no idea where to start on this, is should I be doing scalar projections or something with unit vectors? Have I missed something obvious??
I got really lost and none of my answers came out right (I know the solution, just not how to get to it)
