Question

Find the given vector. Unit vector w in the direction of u = 1, 0, 2

Answer 1

The unit vector w is found by determining the magnitude of u =<1,0,2> and then dividing vector u by it.

The magnitude of v is sqrt(1^2 + 0^2 + 2^2), or √5.

Thus, the unit vector w in the direction of u is    (1/√5)<1,0,2>.
