In Exponential Growth and Decay, Dr. Eaton guides you through the most important formulas and circumstances beginning with decaying by a fixed percentage used in finance. Next is the scientific model of decay which can be used to solve radioactive decay problems. Next is growth by increasing by a fixed percentage followed by the scientific model of growth which can be used to model population growth. Finally are four complete video examples to make sure you can utilize the new concepts and formulas.
If growth or decay is occurring by a fixed percentage during each period of time, use the formula y = a(1 + r)t or y = a(1 – r)t. For scientific applications, use the formula y = aekt or y = ae-kt.
