Question

Consider the vectors
U = (2,1,0) And. V = (2,0,1)

1. Determine the orthogonal projection proj uV
2. Determine the area of the parallelogram determined by u and v

Answer 1

cross product @Msibi

Answer 2

How do one do it

Answer 3

\[proj _{v}u = (\frac{ u . v }{ v.v })*v\]

Answer 4

'The projection of u onto v'

Answer 5

For the area of a parallelogram: |u x v|

Answer 6

Oh, for the projection, that is dot product, not cross product.

Answer 7

Oh thanks I got it
