# Find the magnitude of vector

Answer :

Given

We need to find the magnitude of the vector.

Recall the cross product of two vectors and is

Here, we have (a_{1}, a_{2}, a_{3}) = (0, 4, 3) and (b_{1}, b_{2}, b_{3}) = (1, 1, –1)

Recall the magnitude of the vector is

Now, we find.

Thus, magnitude of vector =
