Question

What is `|| < 9 , 1 , 6 > ||`?

Answer 1

`|| < 9, 1, 6 > || = sqrt(118)`

Explanation:

The general formula for the Euclidean norm of a `3` dimensional vector is given by the formula:

`|| < u, v, w > || = sqrt(u^2+v^2+w^2)`

So in our example:

`|| < 9, 1, 6 > || = sqrt(9^2+1^2+6^2) = sqrt(81+1+36) = sqrt(118)`
