👉 In mathematics, a "divagationally" refers to a mathematical operation in which one variable is varied while another constant remains fixed. This type of operation often occurs when working with partial differential equations or when dealing with non-linear systems. For example, if we have a second-order linear partial differential equation of the form: ∂u/∂x + ∂u/∂y = f(x,y) where u(x, y) is the unknown function and f(x, y) is another constant
