Question

Are the given vectors normal?
a=(5,-2) and b=(6,15)

Answer 1

normal vector have zero dot product

Answer 2

do these vector have zero dot product?

Answer 3

what does that mean?

Answer 4

the dot product of two vectors\[\vec a=\langle x,y,z\rangle\\\vec b=\langle p,q,r\rangle\\\vec a\cdot\vec b=xp+yq+zr\]

Answer 5

um

what

Answer 6

for example, the dot product of (1,2,3) and (4,5,6) is
1*4+2*5+3*6

Answer 7

sooo.. they're normal?

Answer 8

how did you do the problem?

Answer 9

I didn't, I have no idea what to do

Answer 10

the dot product of (a, b) with (x,y) is ax+by
what are your a and b?
what are your x and y?
does the dot product equal zero?
