If `veca = 3hati - 2hatj + hatk` and `vecb = -hati + hatj + hatk,` then the unit vector parallel to `veca + vecb,` is

If veca = (hati - 2hatj -3hatk) and vecb = (2hati + 4hatj +9 hatk) then find a unit vector parallel to (veca + vecb) .

If veca = 3hati+3hatj+hatk and vecb = -2hati+hatj-2hatk then what is the unit vector parallel to veca+vecb

If veca=4hati-hatj+hatk and vecb= 2hati-2hatj+hatk , then find a unit vector parallel to the vector veca + vecb .

If veca =hati + hatj-hatk, vecb = - hati + 2hatj + 2hatk and vecc = - hati +2hatj -hatk , then a unit vector normal to the vectors veca + vecb and vecb -vecc , is

If veca =hati + hatj-hatk, vecb = - hati + 2hatj + 2hatk and vecc = - hati +2hatj -hatk , then a unit vector normal to the vectors veca + vecb and vecb -vecc , is

Given : vecA = 2hati - hatj + 2hatk and vecB = -hati - hatj + hatk . The unit vector of vecA - vecB is

If veca = (-hati + hatj - hatk) and vecb = (2hati- 2hatj + 2hatk) then find the unit vector in the direction of (veca + vecb) .

If veca = (-hati + hatj - hatk) and vecb = (2hati- 2hatj + 2hatk) then find the unit vector in the direction of (veca + vecb) .
