    Finding x-value for vector in a plane defined by two non-parallel vectors

    Eh? That's what the actual question says and that's what I've been taught, anyone able to clarify? Anyway what I've ended up doing is saying if r* was in the plane, it's cross product with either p* or q* (p* x r* etc) would be parallel to p* x q* (p* q* cross product). i.e. they are both...

    Finding x-value for vector in a plane defined by two non-parallel vectors

    Homework Statement Any two vectors that are not parallel define a plane. So p = i + j -k and q = 2i +j define a plane. For what values of x is the vector r = xi + j + k in this plane? Homework Equations The Attempt at a Solution If r* was in the plane formed by p* and q*, would r*...
