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. We assume the body is cooling, then the temperature of the body is decreasing and losing heat energy to the surrounding. Among the civic problems explored are specific instances of population growth and over-population, over-use of natural . So l would like to study simple real problems solved by ODEs. If k < 0, then the variable y decreases over time, approaching zero asymptotically. Innovative strategies are needed to raise student engagement and performance in mathematics classrooms. As you can see this particular relationship generates a population boom and crash the predator rapidly eats the prey population, growing rapidly before it runs out of prey to eat and then it has no other food, thus dying off again.
