The solution finds the area, chord and arc in a circle.
Vector projection and follow-up
The diagram attached shows a rectangular solid, two of whose vertices are A=(0,0,0) and G=(4,6,3).
a) Find vector projections of AG onto the following vectors: AB, [0,1,0], [-1,0,0] and [0,0,1].
b) Find the point on AC that is closest to the midpoint of GH
(The diagram is on page 21 and it is problem 6)
(As you can see I do not need part A of the problem)
