D is its fractal dimension, ranging between 1 and 2 (and typically less than 1.5). More broken coastlines have greater D, and therefore L is longer for the same ε. D is approximately 1.02 for the coastline of South Africa, and approximately 1.25 for the west coast of Great Britain. [5] For lake shorelines, the typical value of D is 1.28. [17]
The first six triangular numbers. The partial sums of the series 1 + 2 + 3 + 4 + 5 + 6 + ⋯ are 1, 3, 6, 10, 15, etc.The nth partial sum is given by a simple formula
The figure shows that 8 can be decomposed into 5 (the number of ways to climb 4 steps, followed by a single-step) plus 3 (the number of ways to climb 3 steps, followed by a double-step). The same reasoning is applied recursively until a single step, of which there is only one way to climb.
Declarative solutions are easier to understand than imperative solutions, [1] [2] and so there has been a long-term trend from imperative to declarative methods. [3] [4] Formula calculators are part of this trend. Many software tools for the general user, such as spreadsheets, are declarative. Formula calculators are examples of such tools.
In general, there exist only four possible cases of quartic equations with multiple roots, which are listed below: [3] Multiplicity-4 (M4): when the general quartic equation can be expressed as () =, for some real number. This case can always be reduced to a biquadratic equation.
Faulhaber's formula is also called Bernoulli's formula. Faulhaber did not know the properties of the coefficients later discovered by Bernoulli. Rather, he knew at least the first 17 cases, as well as the existence of the Faulhaber polynomials for odd powers described below. [2] Jakob Bernoulli's Summae Potestatum, Ars Conjectandi, 1713
The Formula 4 United States Championship is an auto racing series that is held under FIA Formula 4 regulations. The championship is sanctioned by SCCA Pro Racing, the professional racing division of the Sports Car Club of America, in conjunction with the Automobile Competition Committee for the United States, the United States representative to the FIA.
