Can someone start me off on these and please explain step by step how you got everything because I'm having difficulty understanding the entire concept.

Find the projection of u onto v and calculate its magnitude.

a) u = (2,5) v = (6,4)

b) u = (3, 6, -2) v = (-4, 3, 8)

2) If u and v are non zero vectors, but Projection (u unto v) = 0, what conclusion can be drawn?

Would that also mean Projection (v unto u) = 0?

3) Find the projection of PQ onto each of the coordinate axes, where point (2,3,5) and Q is the point (-1,2,5).
