Consider the complex number z=x+ The conjugate of the complex number z=x+ is denoted by z and is defined as z =x-The objective of the problem is to show that z+ z lies on the real axis.Now find z+ z. For that, substitute x+ for z and x- for z in z+z and simplify furth...
The conjugate of the complex number z=x+ is denoted byz and is defined as z=x-.The objective of the problem is to show that z and z have the same modulus.The modulus of a complex number is the distance of the complex number from the origin in a complex plane. The modulus is also...
摘要: Complex number z is an ordered pair of real numbers ( a, b), where [equation]. The first number a is called the real part of the complex number [equation] and is denoted by symbol [equation], while...DOI: 10.1007/978-3-319-92645-2_7 年份: 2018 ...
Def. Ordered SetsLet S be a set. An order on S is a relation, denoted by < , with the following two propeties:(1) If x,y \in S , then either x < y, x=y,y<x is true.(2) If x,y,z \in S , and …
This example shows how to plot complex numbers in MATLAB®. A complex numberzis a number that can be written in the form wherexandyare real numbers, andiis the imaginary unit, which is defined asi2=-1. The numberxis the real part of the complex number, which is denoted byx=Re(z),...

we tentatively assigned cholesterol molecules into the densities at the lower cleft. These cholesterol-like molecules are buttressed by a number of bulky residues, exemplified by Phe283, Phe290 and Phe291 in TCRδ2 and Tyr295 in TCRγ9 at the lower cleft (Fig.3a). The cholesterol-like dens...
The number of 1-order neighbors of node u is called its degree19 and is denoted by k(u), i.e., $$\begin{aligned} k(u)=|\phi (u)|\end{aligned}$$ (2) K-shell hierarchy decomposition The main idea of the K-shell hierarchy decomposition: for a given k, a subgroup of the ...
