A method analogous to piece-wise linear approximation but using only arithmetic instead of algebraic equations, uses the multiplication tables in reverse: the square root of a number between 1 and 100 is between 1 and 10, so if we know 25 is a perfect square (5 × 5), and 36 is a perfect square (6 × 6), then the square root of a number greater than or equal to 25 but less than 36, begins with ...
The simple Dietz method [1] is a means of measuring historical investment portfolio performance, compensating for external flows into/out of the portfolio during the period. [2] The formula for the simple Dietz return is as follows:
The convergence rate of the bisection method could possibly be improved by using a different solution estimate. The regula falsi method calculates the new solution estimate as the x-intercept of the line segment joining the endpoints of the function on the current bracketing interval. Essentially, the root is being approximated by replacing the ...
Simplification is the process of replacing a mathematical expression by an equivalent one that is simpler (usually shorter), according to a well-founded ordering. Examples include:
Also known as the "Sum of the Digits" method, the Rule of 78s is a term used in lending that refers to a method of yearly interest calculation. The name comes from the total number of months' interest that is being calculated in a year (the first month is 1 month's interest, whereas the second month contains 2 months' interest, etc.).
OMB Circular A-21 is a Government circular that sets forth the rules governing the eligibility and calculation of costs in support of sponsored research, development, training and other works produced in agreement with the United States Federal Government, but does not attempt to identify or dictate agency or institutional participation in those works.
The Year Without a Santa Claus, a Christmas special from Jules Bass and Arthur Rankin, Jr., turns 50 this December. The beloved special was adapted from the book of the same name by Phyllis ...
Simplified Cangjie, known as Quick (Chinese: 速成或簡易) is a stroke based [1] keyboard input method based on the Cangjie IME (Chinese: 倉頡輸入法) but simplified with select lists. Unlike full Cangjie, the user enters only the first and last keystrokes used in the Cangjie system, and then chooses the desired character from a list of ...
