## Homework Statement

In three dimensions, consider the vector V = a

_{1}i + a

_{2}j +a

_{3}k. Determine the projections of V onto the x, y, z axis.

## Homework Equations

These are formulas from my textbook related to projection:

All underscores mean subscript.

Proj_A B = (B * A/|A|) A/|A| = ((B * A)/(A * A)) A

B*A = a_1b_1 + a_2b_2 + a_3b_3

Note: The asterisk * in the equation above is the 'dot' used in vector dot products.

PS. Sorry for not using the latex coding to make the equations look nicer. I've used this before and I know how to use the codes but when I submit them the images are broken.

## The Attempt at a Solution

I don't think I'm even close but here's what I did:

(B*A / A*A) A = (a_1 / 1) j = a_1i

That's for the x axis. The projection answers for the other axes I get a_2j and a_3k respectively.
