Problem If A ( 2 , − 1 , 4 ) A(2,-1,4) A ( 2 , − 1 , 4 ) and B ( 5 , 3 , − 2 ) B(5,3,-2) B ( 5 , 3 , − 2 ) , determine the unit vector in the direction from A A A to B B B .
(a) ( − 3 61 , − 4 61 , 6 61 ) \left(-\dfrac{3}{\sqrt{61}}, -\dfrac{4}{\sqrt{61}}, \dfrac{6}{\sqrt{61}}\right) ( − 61 3 , − 61 4 , 61 6 )
(b) ( 3 61 , 4 61 , 6 61 ) \left(\dfrac{3}{\sqrt{61}}, \dfrac{4}{\sqrt{61}}, \dfrac{6}{\sqrt{61}}\right) ( 61 3 , 61 4 , 61 6 )
(c) ( 3 61 , 4 61 , − 6 61 ) \left(\dfrac{3}{\sqrt{61}}, \dfrac{4}{\sqrt{61}}, -\dfrac{6}{\sqrt{61}}\right) ( 61 3 , 61 4 , − 61 6 )
(d) ( 3 13 , 4 13 , − 6 13 ) \left(\dfrac{3}{13}, \dfrac{4}{13}, -\dfrac{6}{13}\right) ( 13 3 , 13 4 , − 13 6 )
