what is the dot product of [tex]G{\bullet}A[/tex] where A = [tex]\left(\frac{a_3}{l}-\frac{{a_1}}{h}\right)[/tex] and G = [tex]2{\pi}h{\frac{{a_2}}x{{a_3}}}{{a_1}{\bullet}{{a_2}}x{{a_3}}}[/tex]

The answer is zero and ive got the worked solution infront of me, i just done see where the [tex]\frac{{{a_3}}}{l}[/tex] goes, the dot product of a vector with itself is 1 isnt it? but then where does the denominator go? and what about the denominator of G?
