WebJul 18, 2024 · As you know, the dot product of two vectors is invariant under rotation, that is why it's called “the scalar product”. The cross product, also called the vector product, transforms as a vector. Now there is a final bit of the puzzle. The magnitude of a vector is also a scalar. Rotating the vector does not change its length. WebApr 15, 2024 · Dot printing, also known as halftone printing, is a printing process that creates images by varying the size and spacing of dots. It’s used primarily for printing photographs or images that have a gradient or continuous tone, as opposed to solid colors. This process involves converting an image into a series of tiny dots that vary in size and ...

WebMar 28, 2016 · As for the dot product of two vectors, based on the law of cosines, you can interpret it as half the difference between the sum of their squares and the square of their difference: ‖→a − →b‖2 = ‖→a‖2 + ‖→b‖2 − 2(→a ⋅ →b). In other words, taking the vectors to be two sides of a triangle, the dot product measures ...
