Understanding the Distance Equation (Formula)

If you want to find the distance between two points, the length of a line, or the magnitude of a vector then you use the distance formula, which usually looks something like this: This is just the Pythagorean Theorem, slightly rearranged. The solution to this problem shows how (with a few steps) it is possible […]
