There is much more to quadratic equations in the modern study of mathematics than geometric applications. What makes an equation quadratic? It is necessary for quadratic equations that the highest power of the variable is 2. If there is no squared term, the equation is not quadratic. Note that...
An equation and the correlated graph for calculating theoretically the geometric mean particle size and an equation for calculating the specific surface area of the particle size distribution of the improved equation are also derived.doi:10.1111/j.1151-2916.1990.tb05210.xJingmin Zheng...

Such finite element methods also fall into the category of geometric methods that have had a considerable success recently. The right framework for this is the so-called finite element exterior calculus (FEEC) introduced by Arnold et al. (2006, 2010). For Maxwell's equations it is based on...
Somewhat later Euclid (c 300 BC) gave a geometric solution, while Al-Kharizmi in the early middle ages described the method of “completing the square” by which the standard formula may be derived. For example he considers the equation (12.3)x2+10x=39 and re-writes this as (x+5)2=...

Even though standard deviation can seem difficult, you should now have the tools to calculate the standard deviation for any set of data. Remember, standard deviation is the measure of how closely all of the data in the data set surrounds the mean. By following these five steps, you can ea...

(I) The problem of “solving algebraic equations by radicals” (where by algebraic equations we mean those of the form f (x) = 0, for f a non-zero polynomial with rational coefficients) was one of the most important topics in mathematics from the earliest periods of antiquity until the ...
