Mathematics Background of the Maxwell equations Let us consider Maxwell equations system: (1) (2) This is a system of the two dependent variables, x and y, which generally depend on independent scalar, i. e. t (say, it be ‘time’).

In the matrix form it is:

dX/dt = A*X, (3) where X = (x; y) is a column of the two coordinates, x and y, on the Descartes’ plane;

A is a 2 x 2 matrix of scalars: a11, a12, a21, a22,

Where a11 = 0; a12 = –1; a21 = 1; a22 = 0. There we understand A*X as a product of matrices A (a 2 x 2 matrix) and X (a 1 x 2 matrix, or a column two-component vector of ...

While it is a good practice to display the trigonometric identities in order to become more familiar with them, it would be better practice to work on some basic identities in order to come up with the other identities. For instance, the Pythagorean identity can be transformed into the other identities. This identity can be divided by the square of sin θ in order to obtain cot²θ + 1 = csc²θ. If tan x = sin x/cos x, then as cot x = 1/tan x, then cot x = cos x/sin x. Furthermore, being able to solve trigonometric problems such as trigonometric equations sometimes requires ...

A1 Quantitative Article

Article #A1: Wu, H., Li, Z., Li, H, & Wu, S. (2016). Quantitative phase imaging of breast cancer cell based on SLIM. Journal of Physics: Conference Series, 679(1), 1-5. doi: 10.1088/1742-6596/679/1/012003

Background

In this article, Wu et al. (2016) used quantitative process in analyzing data created from observing the cell dynamics, in which they used spatial light interference microscopy or SLIM to come up with the data. In this process, they combined the Zernike’s phase contrast microscopy, as well as, Gabor’s holography. Zernicke discovered it back in 1935 when he was able to observe phase objects that did ...

1. The Sine and Cosine graphs are 'complementary', which means that the expression sin2 x + cos2 x = 1 is realized. Therefore, when sin (x) = 1, in that point cos(x) = 0, and vice versa. The same situation is observed when the functions take -1 and 0 values. Therefore, if Sine and Cosine are plotted on the same graphs, they look the same, but as if Cosine function is shifted by pi/2 comparing to Sine. Since Tangent function is obtained as sin x / cos x, then the point x = it should not reach the x-points pi/2, 3pi/2, etc. The ...

Why is there not an opportunity to launch a satellite if the launch-site latitude is greater than the inclination?

The Angle between the projection of the initial orbit plane and the north direction is referred to as the Launch Azimuth, (Dux et al. 2011, pp. 1-16). The Azimuth has several implications to the activities of launching a satellite. It creates three possible windows of launching. The launch window refers to the time during which a launch can be done directly from a specific site into an orbital plane. The window duration is affected by factors like the fuel requirements, safety, and the desired points of injection. The launch window is always at the center of the optimal launch ...

H&M Does it surprise you that the second largest clothing retailer is only selling in stores in 54 countries plus an additional 10 countries online? Why do you think it is not covering more of the world's countries?

during its life cycle, as H&M has been introducing new products like home line (2006) and is now planning to introduce sportswear, which may quickly make H&M a leader in the field thanks to advantages that H&M can boast of in the sportswear category. Moreover, Zara is quite slow in introducing their sportswear category, which gives to H&M the possibility to ...

Integration by parts

Integration by parts is a mathematical technique used in the solving of indefinite and definite integrals. The differential functions of the products are expanded and then expressed in the original integrals (Stroud & Dexter, 70).

The single integration by parts begins with the following:

(uv)' = uv' + u'v and integration of both sides of the equation yields; uv = ∫uv' dx + ∫u'v dx

Rearranging the integrals gives;

∫uv' dx = uv − ∫u'v dx

The key concepts required for easy computation of the integration by parts include;

The choice of dx and dx is such a way that; u is easy to differentiate and dx is easy to integrate. In addition, ∫Vdu and ∫udv should be easy to compute. Sometimes in integration by parts, it is necessary to integrate ...

1. Hippocrates Hippocrates made immense contributions in the world of medicine in the ancient world. The Greek physician lived between (460-377 BCE).Hippocrates is often referred to as the "father of medicine" due to his notable contributions to the medical world. Some of his accomplishments include detailed observation of diseases and an understanding of how diet, body processes, and environment affect health. According to Veatch (2012), Hippocrates was born in Greece on the Island of Cos from a family of doctors. He taught at the highly regarded medical school Cos Island before traveling to the Middle East and other ...
