WebAn equation is any expression with an equals sign, so your example is by definition an equation. Equations appear frequently in mathematics because mathematicians love to use equal signs. A formula is a set of instructions for creating a desired result. Non-mathematical examples include such things as chemical formulas (two H and one O … Webdifference equation, mathematical equality involving the differences between successive values of a function of a discrete variable. A discrete variable is one that is defined or of interest only for values that differ by some finite amount, usually a constant and often 1; for example, the discrete variable x may have the values x0 = a, x1 = a + 1, x2 = a + 2, . . ., xn = …

WebIn this chapter we study the general theory of linear difference equations, as well as direct methods for solving equations with constant coefficients, which give the solution in a closed form. In Section 1 general concepts about grid equations are introduced. Section 2 is devoted to the general theory of mth order linear difference equations. WebAn ordinary differential equation (frequently called an "ODE," "diff eq," or "diffy Q") is an equality involving a function and its derivatives. An ODE of order is an equation of the form.
