May 10: Vector Projections

We spent the first 40 minutes on the quiz. This was the last homework quiz of the year!! But still make sure you're keeping up with your homework because we have a test coming up!

We then looked at the proof for the vector projection of u onto v

(I would type all of the proof except I'm not the best with that equation editor..Ask someone for notes if you need it)
Mr. OB told us that it was not necessary to memorize the proof (he'll put it on the test).

Our homework questions took up the rest of the time.
Example:
#59.
u = <3,5>
Find 2 vectors orthogonal in opposite directions
Possible answers: <-5,3>, <10,-6>
In order to be orthogonal u dot v must equal zero
