## Differential Equations

Applications of Calculus, in particular, differential equations. Differential equations Differential equations differ from normal equations in that the solution is a function, or a set of functions. For example a differential equation is y” + 2y’ – 3y = 0 (example 1) Whereas, an example of a normal equation is x2 – 1 = 0Continue reading “Differential Equations”
