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...
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 …
(z), and the numberyis the imaginary part of the complex number, which is denoted byy=Im(z). You can plot a complex number as a pair of coordinates(x,y)on the complex plane, also known as the Argand diagram. This diagram uses the Cartesian coordinates to represent the real part in...
If the complex number is Z then the modulus is denoted |Z|. The image above shows a chart of the complex plane, complex number 9+12i is the blue line ending with an arrow. The complex plane has an imaginary axis and a real axis, the dashed circle shows the modulus value when it ...
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...

Figure 2d shows the relationship between the slope of rise of the Forman–Ricci network entropy \(H_R(G_t)\) denoted \(a_N(H_R(G_t))\) and the network size N. It is clear that the slope and the size N are positively correlated which aligns with our intuition (for infinitely ...
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 ...
