👉 Detents are a type of mathematical function that is defined on a set of points in the plane. It is also known as the determinant of a matrix or an n×n matrix. In mathematics, a determinant is a special kind of polynomial function whose value at any given point in the plane is the product of its entries along that line. The determinant can be used to find the area and volume of parallelepipeds, to solve systems of linear equations, and many other problems involving matrices.
