Fine two vectors in opposite directions that are orthogonal to the vector u.
Solution:Two vectors are orthogonal if they are perpendicular.
There fore a vector v =(x,y) is orthogonal to u if
(x,y) . (1/2,-2/3) =1/2x-2/3y=0
now I have to find values of x and y that makes 0..?
I am stuck here...plz help? not getting right ans....
