The Composition of Function operator is represented by a small empty circle.
read moreA second-order differential equation is a mathematical equation that involves an unknown function, its first derivative, and its second derivative. In other words, a second-order differential equation takes the form: d^2y/dx^2 = f(x, y, dy/dx) where y is the unknown function, x…

read moreA scalar function is a function of one or more variables whose range is one-dimensional, as compared to a vector function, whose range is three-dimensional (or, in general, n-dimensional).
read moreA scalar is a quantity that has magnitude but no direction. It is a single-dimensional quantity.
