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

If veca = (3hati + hatj - 5hatk) and vecb = (hati + 2hatj - hatk) then find a 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) .

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) .

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

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

If vecA= 6hati- 6hatj+5hatk and vecB= hati+ 2hatj-hatk , then find a unit vector parallel to the resultant of veca & vecB .

If vecA= 6hati- 6hatj+5hatk and vecB= hati+ 2hatj-hatk , then find a unit vector parallel to the resultant of vecA & vecB .

If veca = 2hati -3hatj-1hatk and vecb =hati + 4hatj -2hatk " then " veca xx vecb is

IF veca=2hati-hatj+2hatk and vecb=6hati+2hatj+3hatk , find a unit vector parallel to veca+vecb .
