👉 In mathematics, a folio is a type of curve in three dimensions that can be described by two equations. The first equation defines the location of one point on the curve, and the second equation describes how to move from one point to another along the curve. For example, consider the curve defined by the equation: x^2 + y^2 = 1 This is a circle in three dimensions, but it can be represented as a folio if we specify the location of the center
