Growth and Decay – Informal Calculus

WebExponential Growth and Decay Model If y changes at a rate proportional to the amount present (i.e., dy ky dx = ), and y y= 0 when t = 0, then 0 y y e= kt, where k is the proportionality constant. Exponential growth occurs when k > 0, and exponential decay occurs when k < 0. Example 2. The rate of change of y is proportional to y. When t = 0, y ... WebThese are called the growth and decay equations respectively. And there is a simple solution to the differential equation G′(t) = kG(t) G ′ ( t) = k G ( t). It is G(t) = Aekt G ( t) = A e k t. Let’s see some examples. Decay. A radioactive isotope decays at a rate of 0.003 0.003 times its mass in grams per day. Initially, a sample contains ...
