y=<1,-2,2>=v
v | v | = < 1 , 2 , 2 > | < 1 , 2 , 2 > | = < 1 , 2 , 2 > 1 2 + ( 2 ) 2 + 2 2 = < 1 , 2 , 2 > 1 + 4 + 4 = < 1 , 2 , 2 > 9 = < 1 , 2 , 2 > 3
a unit vector that is parallel to the vector y and is in the same direction
< 1 3 , 2 3 , 2 3 >
to make it going in the opposite directi on, we multiply the unit vector by a scalar -1
( 1 ) < 1 3 , 2 3 , 2 3 >=< 1 3 , 2 3 , 2 3 >
answer:
< 1 3 , 2 3 , 2 3 >

Hi i know this is a really really simple question but it has me confused.
I want to calculate the cross product of two vectors
a×r
The vectors are given by
a=az, r=xx+yy+zz
The vector r is the radius vector in cartesian coordinares.
I want to calculate the cross product in cylindrical coordinates, so I need to write r in this coordinate system.
The cross product in cartesian coordinates is
a×r=ayx+axy,
however how can we do this in cylindrical coordinates?
