The Rules and Equations Associated with the Phi Function
The Phi is described as the number of positive integers less than n
(positive integer) which have no factor, other than 1, in common,
co-prime, with n.
In my investigation I aim to identify and explain the rules and
equations associated with the Phi function. To go about this I will
investigate Φ (n). This will be further touched upon and will help me
investigate and support any conclusions I hope to gain from
investigating whether (a x b) = (a) x (b) in certain cases.

On the second day of class, the Professor Judit Kerekes developed a short chart of the Xmania system and briefly explained how students would experience a number problem. Professor Kerekes invented letters to name the quantities such as “A” for one box, “B” for two boxes. “C” is for three boxes, “D” is for four boxes and “E” is for five boxes. This chart confused me because I wasn’t too familiar with this system. One thing that generated a lot of excitement for me was when she used huge foam blocks shaped as dice. A student threw two blocks across the room and identified the symbol “0”, “A”, “B”, “C”, “D”, and “E.” To everyone’s amazement, we had fun practicing the Xmania system and learned as each table took turns trying to work out problems.
Award-winning author Mandy Hale once stated, “Without negativity, life would be amazing.” However, this statement does not always prove to be true. Today’s modern community generates a judgement that negative experiences will ruin your life, but studies show that negativity can actually result in positive change. For example, negativity can positively change teenagers actions, introduce teenager’s to more supportive environments, and help fix broken relationships.
In this essay I aim to examine the roots of Hasmonean rule and observe the relationship between the regime and `Hellenism' (mainly in the political context), and ascertain to what extent Hellenism became an integrated part of the Hasmonean dynasty's mode of governing its state. It is noteworthy to point out that many scholars explain the process of Hellenization as a long and drawn out one, as Lester Grabbe concisely states; "Hellenization was a centuries-long process of synthesis and diversification. It was not the simple imposition of Greek culture on the natives; indeed, the Greeks on the whole did not impose their culture but rather jealously preserved their `superior' political and cultural position in the Near Eastern society." Another aspect to bear in mind is that Greek coinage was used throughout the land of Palestine during the Persian period and Greek pottery found in the area has been dated as early as the fourteenth century B.C.E. So to suggest that the Greeks and their culture were totally alien to the peoples of Palestine until the arrival of Alexander (and subsequently the Ptolemies and Seleucids) would be to ignore this evidence. This being the case, why was it not until Antiochus IV of the Seleucids that open revolt (and the beginning of the Maccabee's rise to power) in opposition to `Hellenism' occurred? I will attempt to answer this complex question in the course of this essay.
During World War 2 the Nazi were killing the Jews and placing them in concentration camps. It was a dreadful time for the Jewish people. In the story of Anne Frank the Frank family, Van Daan family, and Mr.Dussel hid in the secret annex because they were Jewish. The annex was a hidden section in Mr. Frank’s work building. In order to survive their attitudes and how they act plays a huge part in them working together to survive. Peter a shy boy of the Van Daans and Mr. Dussel a dentist are both loyal to their cause for surviving. Their attitudes are very different compared to each other, Peter is shy and quiet, while Mr. Dussel is loud and talkative. -The differences between Peter and Mr. Dussel’s attitudes impacts how everybody works together to survive.
Infectious diseases had major impacts and influences in the human history. Diseases such as Spanish Influenza or the Bubonic Plague have remarkable positions in history. Disease spread models are used to predict outcomes of an epidemic. These models are used to calculate the impact of an infectious disease, funding required for mass vaccinations and data for public health departments. The earliest mathematical model of infectious diseases was created by Daniel Bernoulli in 1766. This model was used to predict the outcome of inoculation against smallpox disease. In the modern world, these models are created using various software programs. The reason why I chose this subject is because I previously worked on some modelling simulations. Also my father is in the healthcare sector, so this topic looked very exciting to me. Predicting outcomes of infectious epidemics may save thousands of lives and millions of dollars. In the healthcare sector, accuracy and reliability is very important. In this project, the work function of the SIR epidemic model and some of its derivatives will be explored along with some theorems about this models. SIR model is the fundamental model of almost all modern epidemic models. SIR model is the most widely used disease spread model in the world. Also it is a simple epidemic model which has mathematics that commensurate with our class.
The assigned reading was in the Euthyphro. The reading is about Socrates and Euthyphro having a discussion of what piety is. In this paper, I will discuss the moral significance of the question that Socrates proposed. And that is “Is the pious being loved by the gods because it is pious, or is it pious because it is being loved by the gods?”(Prompt). I will start off by giving a brief summary of the reading and then I will move on to the question. In the question I will discuss the moral significance of it and how it affects us in today’s society. Finally, I will end with my conclusion.
With the rise of immigration, English Language Learners (ELL) population is growing fast. By 2025, 25% of the k-12 students will be ELLs. Therefore, a big challenge would be to help such ELLs improve their English language proficiency while there are English-speaking students (non-ELL) in the classes too.
People use numbers whenever they do math. Yet, do they know that each number in the number system has its own unique trait? Numbers such as 4 and 9 are considered square numbers because 2 times 2 is 4, and 3 times 3 is 9. There also prime numbers. Prime numbers are numbers that have exactly two divisors. The number one is not included because it only has one divisor, itself. The smallest prime number is two, then three, then five, and so on. This list goes on forever and the largest known primes are called Mersenne primes. A Mersenne prime is written in the form of 2p-1. So far, the largest known Mersenne prime is 225,964,951-1, which is the 42nd Mersenne prime. This prime number has 7,816,230 digits!
It was hard trying to find a response to the question that is being asked of why I should not be activated into Omega Delta Phi. Because I’m being asked to contradict what I want to say. Well I’m not a perfect person nor do I think I am and sometimes I get sloppy in my work and I make a lot of mistakes at times. I’ve learned to shape my way of thinking into only doing things that will benefit or interest me without the consideration of what others think. I get easily annoyed working with people who are younger than me and that don’t take things on a serious level when needed.
In addition to my academic interest, I also draw, paint, and sculpt in my free time and have taken classes dedicated to this interest. While most might not feel as if that sets them apart, I have used my creativity and abilities in the fine arts to my advantage. My creative edge allows me to carry out creative solutions to problems and labs in class that most others might not realize as a solution. Because of art, I have developed the mindset of analyzing problems by looking at the bigger picture and not only looking at the problem in real life but theoretically.
RSA encryption is the foundation of public key cryptography security products. For example, credit card companies use the RSA algorithm for customers’ individual online WebPages. The credit card companies publish a big number on WebPages, which is made by big prime numbers using the RSA algorithm. Since neither computers nor people can factor such big numbers, the RSA encryption system has secured many customers’ information.
In the reading and in lecture, it was established that Euthyphro has a dilemma with two very different theses. The first thesis is that Things are good because God loves them. What does this mean? I believe what the thesis is hinting at is that no one but God can define what is good or bad. Societal norms shape what we see as good, and what we see as bad. Perhaps God is the almighty author of the society. If He deems something to be good, then everyone accepts it. We cannot use our own judgment to determine one’s “goodness”. But in accordance with the theory, we cannot even control how we judge things. God has given us a predetermined outlook on life, and how we should view certain things. This kind of relates to what we talked about last week in lecture. If how we view things is predetermined, and we are not given the opportunity to make judgments on what is right or wrong, then our essence precedes our existence. In other words, we are not given the chance to form our own opinions, but rather accept what God has determined for us in life because he is almighty. The second thesis is much
Pascal’s Triangle falls into many areas of mathematics, such as number theory, combinatorics and algebra. Throughout this paper, I will mostly be discussing how combinatorics are related to Pascal’s Triangle.
Euclid also showed that if the number 2n - 1 is prime then the number 2n-1(2n - 1) is a perfect number. The mathematician Euler (much later in 1747) was able to show that all even perfect numbers are of this form. It is not known to this day whether there are any odd perfect numbers.
Maxwell’s Equations are a set of four equations that govern all of electromagnetism. The equations show a unification of the electric and magnetic fields and are often considered one of the greatest unifications in physics, describing one of the four fundamental interactions, the electromagnetic force. The unification of the electric and magnetic forces in the 19th century by Maxwell’s Equations led to several scientific advancements – including an entire new branch of physics, electromagnetism – and inventions that transformed the world, consequently providing the world with wide-ranging improvements in quality of life, communications and navigation.
