(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Ais a vector

Show that: a1 = x hat (dot)A

a2 = y hat (dot)A

a3 = z hat (dot)A

2. Relevant equations

A= (a1*x hat) + a2*y hat) + (a3* z hat)

3. The attempt at a solution

my hint says to take the dot product of both sides of the equation in (2) with each of the basis vectors in turn.

Doing this I getA^2 = [(a1*x hat) + a2*y hat) + (a3* z hat)] dotA

I dont know what to do next, or if thats even right.
