Biological exponential growth. Biological exponential growth is the unrestricted growth of a population of organisms, occurring when resources in its habitat are unlimited. Most commonly apparent in species that reproduce quickly and asexually, like bacteria, exponential growth is intuitive from the fact that each organism can divide and ...
List of exponential topics. This is a list of exponential topics, by Wikipedia page. See also list of logarithm topics . Accelerating change. Approximating natural exponents (log base e) Artin–Hasse exponential. Bacterial growth. Baker–Campbell–Hausdorff formula. Cell growth.
Hyperexponential distribution. In probability theory, a hyperexponential distribution is a continuous probability distribution whose probability density function of the random variable X is given by. where each Yi is an exponentially distributed random variable with rate parameter λi, and pi is the probability that X will take on the form of ...
If the constant of proportionality is negative, then the quantity decreases over time, and is said to be undergoing exponential decay instead. The law of exponential growth can be written in different but mathematically equivalent forms, by using a different base, for which the number e is a common and convenient choice:
Gompertz function. The Gompertz curve or Gompertz function is a type of mathematical model for a time series, named after Benjamin Gompertz (1779–1865). It is a sigmoid function which describes growth as being slowest at the start and end of a given time period. The right-side or future value asymptote of the function is approached much more ...
The stretched exponential function. is obtained by inserting a fractional power law into the exponential function . In most applications, it is meaningful only for arguments t between 0 and +∞. With β = 1, the usual exponential function is recovered. With a stretching exponent β between 0 and 1, the graph of log f versus t is ...
The growth or decay constant in exponential growth or exponential decay, respectively. Topics referred to by the same term This disambiguation page lists mathematics articles associated with the same title.
Quadratic growth. In mathematics, a function or sequence is said to exhibit quadratic growth when its values are proportional to the square of the function argument or sequence position. "Quadratic growth" often means more generally "quadratic growth in the limit ", as the argument or sequence position goes to infinity – in big Theta notation ...
