If a = i - 2j + 2k

b = 4i - 3j

M = 3ii + 2ij - ji + kj. M is a dyadic.

Determine a[itex]\bullet[/itex]2M[itex]\bullet[/itex]b

2. Relevant equations

3. The attempt at a solution

This isn't really homework, but rather just some self study to help me understand some of my work better. Attached is the answer.

My real question in this case is some info on how the dot product works? Been trying to find some info about this for 2 days now. If someone could just help explain the dot product between a and 2M, I would be really greatful.

Thanks
