Question

what is the formula of magnitude of vector​

Answer 1

Answer:

The formula for the magnitude of a vector can be generalized to arbitrary dimensions. For example, if a=(a1,a2,a3,a4) is a four-dimensional vector, the formula for its magnitude is ∥a∥=√a21+a22+a23+a24.

Answer 2

Explanation:

The magnitude of a vector PQ is the distance between the initial point P and the end point Q . In symbols the magnitude of vector PQ is written as modules Vector PQ.

Modules vector PQ = under root (x2 - x1) ^2 + (y2 - y1) ^2

For a three-dimensional vector a=(a1,a2,a3), the formula for its magnitude is

modules A =

under root (A1^2 + A2^2 + A3^2)
