Answer 5

YOu have a formula for this. Look up your notes and tell me what it is.

Answer 6

i couldnt find it

Answer 7

Why? then google it

Answer 8

\[\cos \Theta = V \times W / \left| V \right| \left| W \right|\]

Answer 9

that? @Loser66

Answer 10

Not really.
It is \(cos (\theta) =\dfrac{<v, w>}{||v||*||w||}\)

Answer 11

The numerator is "dot" product of v and w
Hence, in your case , it is u and v. Now rewrite it, please.

Answer 12

so the denominator would be 36?
