What is the first order differential equation for exponential growth?

Application 1 : Exponential Growth – Population. Let P (t) be a quantity that increases with time t and the rate of increase is proportional to the same quantity P as follows. d P / d t = k P. where d p / d t is the first derivative of P, k > 0 and t is the time. The solution to the above first order differential equation is given by.
