Get the norm of a vector

WebIf I want to find a normal vector, I can find the slope of the line and then do the opposite reciprocal to find a normal vector. By=-Ax+C y=-A/B*x+C/B. The slope is -A/B. A normal vector will have slope B/A. An easy way to construct this is to make the y comp = B and the x comp = A. Thus, the vector normal the line Ax+By=C is [A, B]. WebA few formulas; if a vector x → = ( x 1, x 2, …, x n), then its norm or length is given by: ‖ x → ‖ = x 1 2 + x 2 2 + … + x n 2 Note that ‖ x → ‖ is not a vector, but a real number. If x → ≠ 0 →, then ‖ x → ‖ ≠ 0 and you can divide: 1 ‖ x → ‖ x → The resulting vector has the same direction as x →, but has length 1 since:
