Point Vector Recipe
=======================

A point vector is a mathematical concept used in linear algebra and computer graphics. It represents a direction from one point to another.

Recipe:

1. Define the points: Identify two points in 3D space, P1 and P2.
2. Calculate the difference: Find the difference between the coordinates of P2 and P1, resulting in a vector v = P2 - P1.
3. Normalize the vector (optional): If desired, normalize the vector to have a length of 1.

Example Code (JavaScript)

function pointVectorRecipe(P1, P2) {
  const v = [P2[0] - P1[0], P2[1] - P1[1], P2[2] - P1[2]];
  return v;
}

// Example usage:
const P1 = [1, 2, 3];
const P2 = [4, 5, 6];
const vector = pointVectorRecipe(P1, P2);
console.log(vector); // Output: [3, 3, 3]

Note that this recipe assumes a 3D space. If you're working in a different dimension or coordinate system, adjust the formula accordingly.
