Itâs just impossible heâs not an INTJ. I see a lot of myself in House, from the shallow little traits to all his deepest struggles. In fact, watching the show was what recently made me become interested in psychology and Jungian/MBTI theories.
Dot Product. The dot product, or scalar product, of two vectors is equal to the sum of the products of the corresponding coordinates in each vector. If a = (x,y,z) and b = (u,v,w), then the dot product is aÂ·b = x u + y v + z*w. vector is a quantity with magnitude and direction. For example a wind speed vector says how fast the wind is blowing, as well as in what direction. The easiest way to calculate the angle between two different vectors is by using the dot product.
Using Cross-Product and Vectors to find the distance between parallel lines ? Sep 11, 2011 #1. Given the following two lines, prove that they are parallel, then find the distance between them... (I have circled in red the two parts of the answer which I don't understand. Namely, why are they using the cross-product here, doesn't that give you a value perpendicular to the lines, hence a new vector that is on the parallel planes of the lines? The second part I highlighted I have no idea why they chose this.)
