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.
Typically for vectors the two numbers are a magnitude and a direction. For a displacement vector from the origin, this is the length (r in the example below) and the angle Î¸ measured counter clockwise from the x-axis. This is equivalent to giving the polar coordinates of the point at the head of the vector.
