Unformatted text preview: y = z . Now, to make c a unit vector, we need x 2 + y 2 + z 2 = 1, then 3 x 2 = 1, after plugging in the identity we just arrived. then , x = √ 3 3 , y =√ 3 3 , and z = √ 3 3 , or x =√ 3 3 , y = √ 3 3 , and z =√ 3 3 , i.e c = < √ 3 3 ,√ 3 3 , √ 3 3 > , or c = <√ 3 3 , √ 3 3 ,√ 3 3 >...
