Question

Unit vector along the direction of line 2(x-2)=(y+1)=(3-1) is​

Answer 1

Answer:

If point P is (2,4,4) and Q is (-3,2,2), the vector PQ would be (-5,-2,-2). To find the unit vector, divide vector PQ by its magnitude. ∣∣∣∣∣∣−−→PQ∣∣∣∣∣∣ would be √(−5)2+(−2)2+(−2)2)=√33. Hence unit vector would be

(1√33)⎛⎜⎝−5−2−2⎞⎟⎠
