First norm of 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]. WebOct 4, 2014 · Well, if you want to find the norm of a vector, all you have to do is uniformly scale the unit ball up until it just barely touches the vector, then that scaling factor is the norm of the vector. This follows from the scaling property of norms. (See Minkowski functional for this statement in more technical wording.)
