![Find unit vectors that satisfy the stated conditions.
NOTE: Enter the exact answers in terms of i,j and k.
(a) Same direction as
2i + 9j.
-
u =-21 i + 0.977 j
(b) Оррositelyу directed to 6i - 3j + 12k.
v =-0.43 i + 0.21 j – 0.87 k
(c) Same direction as the vector from the point A(-2,0, 2) to the point
В(2, 1, 1).
