  2. Exponential growth - Wikipedia

    Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself.

  3. Biological exponential growth - Wikipedia

    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 produce two copies of itself.

  4. Talk:Exponential growth - Wikipedia

    i see it mention but the formula itself is not mentioned, so: Q (t)=a (1+r)^t where. the coefficient a is the initial value of Q (at t = 0) the base b is the growth factor where + b = 1 + r is growth (b > 1) where r is the rate (as a decimal) the exponent t is the independent variable.

  5. Exponential function - Wikipedia

    The exponential function is a mathematical function denoted by or (where the argument x is written as an exponent ). Unless otherwise specified, the term generally refers to the positive-valued function of a real variable, although it can be extended to the complex numbers or generalized to other mathematical objects like matrices or Lie algebras.

  6. Exponential distribution - Wikipedia

    In probability theory and statistics, the exponential distribution is the probability distribution of the time between events in a Poisson point process, i.e., a process in which events occur continuously and independently at a constant average rate. It is a particular case of the gamma distribution.

  7. Characterizations of the exponential function - Wikipedia

    The six most common definitions of the exponential function exp (x) = ex for real x are: Define ex by the limit Define ex as the value of the infinite series (Here n! denotes the factorial of n. One proof that e is irrational uses a special case of this formula.) Define ex to be the unique number y > 0 such that

  8. Malthusian growth model - Wikipedia

    A Malthusian growth model, sometimes called a simple exponential growth model, is essentially exponential growth based on the idea of the function being proportional to the speed to which the function grows. The model is named after Thomas Robert Malthus, who wrote An Essay on the Principle of Population (1798), one of the earliest and most ...
