Even though it does not consider numerous variables like immigration and emigration, which can cause human populations to increase or decrease, it proved to be a very reliable population predictor. For such a system, the independent variable is t (for time) instead of x, meaning that equations are written like dy dt = t 3 y 2 instead of y = x 3 y 2. Several problems in engineering give rise to partial differential equations like wave equations and the one-dimensional heat flow equation. A.)
