Question

Let v1 = (-6,4) and v2 = (-3,6). Compute the following.
-The angle between v1 and v2.

I already have calculated v1 x v2 to be 6.

Answer 1

then divide by the product of the norms of each vector

Answer 2

\[||v_1||=\sqrt{6^2+4^2}\] is a start

Answer 3

that will be the cosine of your angle
to find the angle, take the arccosine of the result

Answer 4

btw your dot product is wrong
it is \(42\)
