Ordinary Differential Equations in Real World Situations Differential equations have a remarkable ability to predict the world around us. For example, as predators increase then prey decrease as more get eaten. Moreover, we can tell us how fast the hot water in pipes cools off and it tells us how fast a water heater cools down if you turn off the breaker and also it helps to indicate the time of death given the probable body temperature at the time of death and current body temperature. To solve a math equation, you need to decide what operation to perform on each side of the equation. This requires that the sum of kinetic energy, potential energy and internal energy remains constant. However, differential equations used to solve real-life problems might not necessarily be directly solvable.
