Therefore, the exponential growth formula we should use is: What should you do to calculate the projected population size in the year 2030? From the given data, we can conclude the initial population value, x 0, equals 10,000. It was noticed that the population of the city grows at a steady rate of 5% annually. For more examples of where you can use this formula, please check below.Ĭonsider the following problem: the population of a small city at the beginning of 2019 was 10,000 people. To learn more, please see our compound interest calculator. The exponential growth equation is used in radiocarbon dating, PCR (you can discover why with our annealing temperature calculator) as well as in calculating compound interest. The reason for this is that you cannot have a decline of more than 100% with regards to the initial quantity, as it would result in a negative value. Note that the exponential growth rate, r, can be any positive number, but, this calculator also works as an exponential decay calculator - where r also represents the rate of decay, which should be between 0 & -100%. The exponential function appearing in the above formula has a base equal to 1 + r/100. Is used when there is a quantity with an initial value, x 0, that changes over time, t, with a constant rate of change, r. The general rule of thumb is that the exponential growth formula:

Hover the mousse cursor on the top right of the graph to have the option of download the graph as a png file.There is a substantial number of processes for which you can use this exponential growth calculator.

Hover the mousse cursor on the graph to read the value of the time t and the y coordinate which is equal to the value of the function a(t). Similarly for the parameters r1 and r2, start with small values (0.001, 0.02, 0.03.) and increase them to understandt their effects on the behaviour of the function.

) of the time interval and increase it to understand the behaviour of the function for small values of t, and then increase t to understand the behaviour of the same function for larger values of time. Time t is entered as an interval of time starting from zero. This calculator uses two functions of the exponential growth type where the parameters of each one may be set at values desired.Įnter the initial amount A1 and the rate of decrease r1 (positive) for the first function a 1(t) and the amount A2 and rate of decrease r2 (positive) for the second function a 1(t) then press the button 'Graph'.

The use of this grapher helps you understand the behaviour of exponential growth functions as time t increases by comparing several functions with different parameters.

How to use the Exponential Growth Calculator and Grapher In order to understand the effect of each of the two parameters, we need to fix one of the parameters, r for example with r1 = r2, and assign different values to A1 and A2 which makes it easy to understand the effect of A. One way to better understand exponential growth functions is to compare two or more of these functions with different parameters A and r. Therefore a thorough understanding of this class of functions is necessary for their proper applications. Because the exponent r t is positive, the above function increases as the time t increases.Įxponential growth functions have various applications in electricity, physics, chemistry, eletricity, economics and many other fields. Where A is the initial amount to model, r (positive) is the rate of increase and t is the time.
