They are used in many applications like to explain thermodynamics concepts, the motion of an object to and fro like a pendulum, to calculate the movement or flow of electricity. Growth and Decay. If k < 0, then the variable y decreases over time, approaching zero asymptotically. hbbd``b`z$AD `S Example 14.2 (Maxwell's equations). 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. As with the Navier-Stokes equations, we think of the gradient, divergence, and curl as taking partial derivatives in space (and not time t). This differential equation is considered an ordinary differential equation. When \(N_0\) is positive and k is constant, N(t) decreases as the time decreases. This function is a modified exponential model so that you have rapid initial growth (as in a normal exponential function), but then a growth slowdown with time.
