Given vectors u = (u1, u2), v = (v1, v2), and w =(w1, w2), determine whether the result of the following expression is a vector or a scalar.

Question

hartnn · Answer

dot product gives a scalar, 
cross product gives a vector.

hartnn · Answer

addition or subtraction will give a vector.....

jim_thompson5910 · Answer

you can only take the cross product in R3, so I don't think the cross product will be used here

anonymous · Answer

so its a scalar?

jim_thompson5910 · Answer

what is the expression?

hartnn · Answer

depends on expression

anonymous · Answer

well the expression is u = (u1, u2) v = (v1, v2) w = (w1, w2)

hartnn · Answer

those are given vectors, not expression....

anonymous · Answer

i know how to use the dot product but the vectors do not have any numbers with them

hartnn · Answer

do u have choices ? because i don't see any expression there...

anonymous · Answer

my only choices are vector or scalar

hartnn · Answer

' the following expression '
is there an expression that follows ? 
i suggest u take a screenshot of your question....

hartnn · Answer

entire question.

anonymous · Answer

okay let me do that
