First Order Differential Equations In “real-world,” there are many physical quantities that can be represented by functions involving only one of the four variables e.g., (x, y, z, t) Equations involving highest order derivatives of order one = 1st order differential equations Examples: macroeconomic applications. Generally, $\frac{dQ}{dt} = \text{rate in} – \text{rate out}$ Typically, the resulting differential equations are either separable or first-order linear DEs. A second order differential equation involves the unknown function y, its derivatives y' and y'', and the variable x. Second-order linear differential equations are employed to model a number of processes in physics. Some of the uses of ODEs are: 1. For that we need to learn about:-. As t increases without bound, x(t) converges to b/a if a > 0, and grows without bound if a < 0 and x 0 ≠ b/a. 5) They help economists in finding optimum investment strategies.
