Question

How do I go about to approach this vector theorem? I will attach the image.

Answer 1

well, what does it mean to be parallel to a plane?

Answer 2

would you agree that the xz plane has a constant y value at y=0? if so, then what property would a parallel plane have?

Answer 3

wait, mighta read the question to fast

Answer 4

think of a curve that is equidistant from the origin and the x aixs

Answer 5

let the vector u be defined by (a,b,c)

then y = |u| for all vectors u

Answer 6

p = (a,sqrt(a^2+b^2+c^2),c)
