## CS代写|计算机图形学作业代写computer graphics代考|Infinity

The term infinity is used to describe the size of unbounded systems. For example, there is no end to prime numbers: i.e. they are infinite; so, too, are the sets of other numbers. Consequently, no matter how we try, it is impossible to visualise the size of infinity. Nevertheless, this did not stop Georg Cantor from showing that one infinite set could be infinitely larger than another.

Cantor distinguished between those infinite number sets that could be ‘counted’, and those that could not. For Cantor, counting meant the one-to-one correspondence of a natural number with the members of another infinite set. If there is a clear correspondence, without leaving any gaps, then the two sets shared a common infinite size, called its cardinality using the first letter of the Hebrew alphabet aleph: $\aleph$. The cardinality of the natural numbers $\mathbb{N}$ is $\aleph_0$, called aleph-zero.

Cantor discovered a way of representing the rational numbers as a grid, which is traversed diagonally, back and forth, as shown in Fig. 2.5. Some ratios appear several times, such as $\frac{2}{2}$, $\frac{3}{3}$ etc., which are not counted. Nevertheless, the one-toone correspondence with the natural numbers means that the cardinality of rational numbers is also $\aleph_0$.

A real surprise was that there are infinitely more transcendental numbers than natural numbers. Furthermore, there are an infinite number of cardinalities rising to $\aleph_s$. Cantor had been alone working in this esoteric area, and as he published his results, he shook the very foundations of mathematics, which is why he was treated so badly by his fellow mathematicians.

## CS代写|计算机图形学作业代写computer graphics代考|Background

Modern algebraic notation has evolved over thousands of years where different civilisations developed ways of annotating mathematical and logical problems. The word ‘algebra’ comes from the Arabic ‘ $a l$-jabr w’al-muqabal’ meaning ‘restoration and reduction’. In retrospect, it does seem strange that centuries passed before the ‘equals’ sign (=) was invented, and concepts such as ‘zero’ (CE 876) were introduced, especially as they now seem so important. But we are not at the end of this evolution, because new forms of annotation and manipulation will continue to emerge as new mathematical objects are invented.

One fundamental concept of algebra is the idea of giving a name to an unknown quantity. For example, $m$ is often used to represent the slope of a 2D line, and $c$ is the line’s $y$-coordinate where it intersects the $y$-axis. René Descartes formalised the idea of using letters from the beginning of the alphabet $(a, b, c, \ldots)$ to represent arbitrary quantities, and letters at the end of the alphabet $(p, q, r, s, t, \ldots, x, y, z)$ to represent quantities such as pressure $(p)$, time $(t)$ and coordinates $(x, y, z)$.

With the aid of the basic arithmetic operators: $+,-, \times, /$ we can develop expressions that describe the behaviour of a physical process or a logical computation. For example, the expression $a x+b y-d$ equals zero for a straight line. The variables $x$ and $y$ are the coordinates of any point on the line and the values of $a, b$ and $d$ determine the position and orientation of the line. The $=$ sign permits the line equation to he expressed as a self-evident statement:
$$0=a x+b y-d .$$
Such a statement implies that the expressions on the left- and right-hand sides of the = sign are ‘equal’ or ‘balanced’, and in order to maintain equality or balance,whatever is done to one side, must also be done to the other. For example, adding $d$ to both sides, the straight-line equation becomes
$$d=a x+b y .$$
Similarly, we could double or treble both expressions, divide them by 4 , or add 6 , without disturbing the underlying relationship. When we are first taught algebra, we are often given the task of rearranging a statement to make different variables the subject. For example, (3.1) can be rearranged such that $x$ is the subject:
\begin{aligned} y &=\frac{x+4}{2-\frac{1}{z}} \ y\left(2-\frac{1}{z}\right) &=x+4 \ x &=y\left(2-\frac{1}{z}\right)-4 . \end{aligned}
Making $z$ the subject requires more effort:
\begin{aligned} y &=\frac{x+4}{2-\frac{1}{z}} \ y\left(2-\frac{1}{z}\right) &=x+4 \ 2 y-\frac{y}{z} &=x+4 \ 2 y-x-4 &=\frac{y}{z} \ z &=\frac{y}{2 y-x-4} \end{aligned}
Parentheses are used to isolate part of an expression in order to select a subexpression that is manipulated in a particular way. For example, the parentheses in $c(a+b)+d$ ensure that the variables $a$ and $b$ are added together before being multiplied by $c$, and finally added to $d$.

$$0=a x+b y-d .$$

$$d=a x+b y .$$

$$y=\frac{x+4}{2-\frac{1}{z}} y\left(2-\frac{1}{z}\right) \quad=x+4 x=y\left(2-\frac{1}{z}\right)-4 .$$

$$y=\frac{x+4}{2-\frac{1}{z}} y\left(2-\frac{1}{z}\right) \quad=x+42 y-\frac{y}{z}=x+42 y-x-4 \quad=\frac{y}{z} z=\frac{y}{2 y-x-4}$$
