Mar 20, 2023 #2 jedishrfu Mentor Insights Author 14,376 8,470 The absolute value bars indicate the length of the vector not absolute value of a number. Of course, the vector length is always positive. I think this convention was more popular in early vector math books where as now they use the double v-bar notation. https://en.wikipedia.org/wiki/Norm_(mathematics)
