👉 The term "coexpanded" is a mathematical concept in linear algebra and vector calculus, which refers to the process of expanding or contracting a vector field. Specifically, it involves multiplying a vector by its own covector product. In other words, if we have two vectors (x1, y1) and (x2, y2), they can be expanded into a new vector (x1x2, x1y2 + y1x2), where the cross product of the two
