Weblaw of natural growth (if k > 0) or the law of natural decay (if k < 0). Because it is a separable differential equation we can solve it. 7 Exponential Growth and Decay = k dt ln y = kt+ C y = ekt+C= eCekt y = Aekt where A (= eCor 0) is an arbitrary constant. To see the significance of the constant A, we observe that y(0) = Aek 0= A Webk = relative decay rate that is constant. Note that k > 0. t = the time the population decays. P(t) = the population that is left after time t. Notes 1. Many times the rate of decay is expressed in terms of half-life, the time it takes for half of any given quantity to decay so that only half of its original amount remains. 2. folydol m tabWebGrowth and Decay Problems Dinkar P.
