    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):

  3. 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:

  4. Terminal value (finance) - Wikipedia

    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. Gay-Lussac's law - Wikipedia

    Gay-Lussac used the formula acquired from ΔV/V = αΔT to define the rate of expansion α for gases. For air, he found a relative expansion ΔV/V = 37.50% and obtained a value of α = 37.50%/100 °C = 1/266.66 °C which indicated that the value of absolute zero was approximately 266.66 °C below 0 °C.

  6. 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 ...

  7. 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.

  8. Perpetuity - Wikipedia

    en.wikipedia.org/wiki/Perpetuity

    A perpetuity is an annuity in which the periodic payments begin on a fixed date and continue indefinitely. It is sometimes referred to as a perpetual annuity. Fixed coupon payments on permanently invested (irredeemable) sums of money are prime examples of perpetuities. Scholarships paid perpetually from an endowment fit the definition of ...

  9. Exponential growth - Wikipedia

    Also, the effects of Moore's Law do not help the situation much because doubling processor speed merely increases the feasible problem size by a constant. E.g. if a slow processor can solve problems of size x in time t, then a processor twice as fast could only solve problems of size x + constant in the same time t. So exponentially complex ...
