Dot product :o

Answer 3

I'm guessing you don't know what dot product is. .-.

Answer 4

The denominator is actually v dot v.

Answer 5

Omg I messed up the formula, hold on.

Answer 6

\[proj_v u = \frac{u.v}{v.v}v\]
The projection of u onto v

Answer 7

Yeah, you'll have to do that for the numerator and denominator. Then multiply that quotient by vector v.

Answer 8

For what?

Answer 9

Omg, I screwed up the dot product formula. >:l
\[<X1,Y1>.<X2,Y2> = X1*X2 + Y1*Y2\]
