  2. Sum of perpetuities method - Wikipedia

    en.wikipedia.org/wiki/Sum_of_Perpetuities_Method

    SPM is derived from the compound interest formula via the present value of a perpetuity equation. The derivation requires the additional variables and , where is a company's retained earnings, and is a company's rate of return on equity. The following relationships are used in the derivation:

  3. Dividend discount model - Wikipedia

    en.wikipedia.org/wiki/Dividend_discount_model

    a) When the growth g is zero, the dividend is capitalized. =. b) This equation is also used to estimate the cost of capital by solving for . = +. c) which is equivalent to the formula of the Gordon Growth Model (or Yield-plus-growth Model):

  4. Terminal value (finance) - Wikipedia

    en.wikipedia.org/wiki/Terminal_value_(finance)

    Also, the perpetuity growth rate assumes that free cash flow will continue to grow at a constant rate into perpetuity. Consider that a perpetuity growth rate exceeding the annualized growth of the S&P 500 and/or the U.S. GDP implies that the company's cash flow will outpace and eventually absorb these rather large values. Perhaps the greatest ...

  5. List of equations in classical mechanics - Wikipedia

    en.wikipedia.org/wiki/List_of_equations_in...

    Classical mechanics is the branch of physics used to describe the motion of macroscopic objects. [1] It is the most familiar of the theories of physics. The concepts it covers, such as mass, acceleration, and force, are commonly used and known. [2] The subject is based upon a three-dimensional Euclidean space with fixed axes, called a frame of ...

  6. Hooke's law - Wikipedia

    en.wikipedia.org/wiki/Hooke's_law

    In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring.

  7. List of mathematical constants - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical_constants

    A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1] For example, the constant π may be defined as the ratio of the length of a circle's circumference to ...

  8. Conserved quantity - Wikipedia

    en.wikipedia.org/wiki/Conserved_quantity

    A conserved quantity is a property or value that remains constant over time in a system even when changes occur in the system. In mathematics, a conserved quantity of a dynamical system is formally defined as a function of the dependent variables, the value of which remains constant along each trajectory of the system.

  9. Relative growth rate - Wikipedia

    en.wikipedia.org/wiki/Relative_growth_rate

    If the RGR is constant, i.e., =, a solution to this equation is = ⁡ Where: S(t) is the final size at time (t). S 0 is the initial size. k is the relative growth rate. A closely related concept is doubling time.
