two function formulas can be easily used to illustrate the concepts of growth and decay in applied situations. If a quantity grows by a fixed percent at regular intervals, the pattern can be depicted by these functions. Exponential Growth: y = a(1 +r)x Exponential Decay: y = a(1 -r)x...
Growth and DecayBut sometimes things can grow (or the opposite: decay) exponentially, at least for a while.So we have a generally useful formula:y(t) = a × ekt Where y(t) = value at time "t" a = value at the start k = rate of growth (when >0) or decay (when <0) t =...

decayexponentialgrowthlny指数衰减 Exponential Growth and Decay Recall that if y = f(t), then f (t) = dy dt is called the rate of change of y with respect to t. Another very important measure of rate of change is the relative rate of change f (t) f(t) = y y . If this quantit...
Exponential Growth and Decay 气生根 Exponential Growth and Decay Suppose y=ekx. Then dy/dx=kekx. Since y=ekx, dy/dx=ky. This is an example of a differential equation. If y=2ekx, then dy/dx=2kekx, which is once again equal to ky. More generally, if y=Aekx, then dy/dx=Akekx,...
