Theory of Parabolas Essay Example for Free
Theory of Parabolas Essay A parabola is designed on a basic formula, Y=ax^2+bx+c, which allows it to achieve a curve not seen in a normal line graphed using a Y=mx+b format. To the left is a graph whoââ¬â¢s formula is y=x^2, where a=1, b=0, and c=0. I have isolated the (a) factor to see its effects on the parabola. Below is a graph where I have changed the (a) multiple times. The result is that as the (a) decreases, the mouth of the parabola widens due to the fact that (a) is essentially the slope of the parabola. Now, watch what happens when the (a) becomes negative. Now the mouth of the parabola is opening down and as we increase (a), the parabola widens. When (a)1, the parabola closes up horizontally. So from this, we can infer that if (a) is 0, then the result will be a straight line going along the X axis which is no longer a parabola. Now we will look at how the (b) factor changes the parabola, below is the origional graph from the top of the paper except the red line represents the same parabola with a (b) added onto it. The original equation was Y=x^2(blue line) and the new equation is Y=x^2+x(red line). The change is moving the vertex of the parabola left ? and down ? but the shape of the parabola itââ¬â¢s self is unchanged. Here are some other examples of changing (b) in a parabola with a steady (a) As seen in the graph, (b) only moves the parabola to the sides and down (as the numbers increase, the vertex moves left and down and decreasing is vice versa), but somehow fails to move the parabola up past the point X=0 on its own (making the (a) negative will flip the parabola). So now we have a slope (a) and a vertex (b), but we still need our Y-intercept which will be our (c) As shown from the graph, our parabolas Y-intercepts match up with our (c) factor, completing the equation -Fun fact, the word parabola came from the Greek words para, meaning beside, and bole, meaning to throw

Taking Our Freedom for Granted Essay -- United States History Historic
Taking Our Freedom for Granted Our country was founded on the idea of freedom: freedom from a king, freedom to believe in whatever one wants to believe in and freedom to openly express these beliefs with others. Through careful examination of what the authors during this period of history were expressing, I have found a greater respect for our freedoms. Thomas Jefferson, Benjamin Franklin and Thomas Paine are all familiar names to high school students in the United States. However, their principles are not familiar and I was shocked to learn that I had not previously read a majority of the works these men created to provide a foundation for our countryââ¬â¢s belief system. Due to these works, I realize how much I have taken our freedom for granted. These men had radical ideas: the government canââ¬â¢t impose a religion on us, religion has nothing to do with the church and questioning oneââ¬â¢s beliefs is vital to their faith. While learning where our countryââ¬â¢s religious roots were first planted, Iââ¬â¢ve also learned just how important it is to question and probe everything weââ¬â¢re told. Why do I go to church? Because Iââ¬â¢m supposed to, because my parents do, because thatââ¬â¢s the ââ¬Å"ruleâ⬠set by my religion. If I were to stop attending church, I would be a bad Christian. However, isnââ¬â¢t it true that if I attend church yet do not truly believe in what Iââ¬â¢m doing, this is just as bad? Paine wrote, ââ¬Å"When a man has so far corrupted and prostituted the chastity of his mind, as to subscribe his professional belief to things he does not believe, he has prepared himself for the commission of every oth er crimeâ⬠(644). I believe Paine is saying that to tell yourself that you do believe in attending church when you know deep inside you are having doubts and... ... would be found deeply embedded in freedom and equality. The British governmentââ¬â¢s hostile ways in forcing a religion upon the people can be seen as horrible and yet, it was the very thing that allowed our country to strive so purposefully towards the freedom to believe anything one wants. Certain situations that seem bad can also ââ¬Å"â⬠¦bring things and men to light, which might otherwise have lain forever undiscoveredâ⬠(966), as Paine wrote. And without these discoveries, we would be a people bound to a leader and dependent on everything that is told to us. Instead, we have become a people of great diversity, in both culture and belief, appearance and demeanor, and we refuse to give up this freedom that our founding fathers established. For, as Paine wrote, ââ¬Å"â⬠¦he whose heart is firm, and whose conscience approves his conduct, will pursue his principles unto deathâ⬠(969).

David Hockingââ¬â¢s book The Nature of God in Plain Language Essay
It has to be said that the concept of trust has taken quite a hammering in society in the past twenty years.à During this time we have seen a host of previously considered ââ¬Å"credibleâ⬠people such as politicians, priests, childcare workers, teachers, babysitters and more exposed in the media as liars, cheats and criminals so is it any wonder that we might have trouble believing in an entity that has never actually been seen by anyone ââ¬â someone like God for example.à David Hocking examines this issue of trust in relation to faith in his book The Nature of God in Plain Language. à à à à à à à à à à à One of the key factors illustrated in Hockingââ¬â¢s book is the fact that the Bible clearly states that God made man ââ¬Å"in his own imageâ⬠, so therefore God should be viewed as we might view other people around us, or perhaps more specifically in the way we view ourselves.à à Hocking makes it clear that God is not some form of ââ¬Å"forceâ⬠but that instead he can be viewed to be a person like us, and therefore if we want to learn more about God then we can learn about him through looking at ourselves.à Hocking writes, ââ¬Å"He possesses life, self-consciousness, freedom, purpose, intelligence and emotionâ⬠(65). One of the problems that stems from this viewpoint is that many people walk around with a very low opinion of themselves so it might be difficult to understand that while God is not ââ¬Ëbetterââ¬â¢ than us, and therefore be considered as some paragon of perfection, he is an image of the very ââ¬Å"bestâ⬠that we could be to ourselves, for ourselves and to others. Hocking reinforces the fact about being a ââ¬Å"friend of Godâ⬠and points to the example of Abraham in the Old Testament who is cited as being a person who did look upon God, and did consider God to be his friend. We are not capable of being friends with a force, or source of higher power, which is why it is important for non-believers to understand that God does have elements of humanity, which we as humans share.à But the distance that is often perceived between God and man does help perpetuate the elements of mistrust about God as a creator of life, God as a loving father and God as the keeper of all men, especially if our own experience with trusting other human individuals has left us so cynical or jaded about the good in mankind Hocking believes that our growing cynicism is why trust is such an important concept when discussing a relationship with God. We should be able to trust our friends, our partners, and our family and this same trust needs to be found in God if he is to provide a positive influence in our own lives. Hocking illustrates the common problem we have as trusting individualââ¬â¢s when he explains about a woman that had been abused and let down continually by the significant people in her life including her parents that placed her in an institution, to friends and significant others she met throughout her life.à If she had been let down by so many people in her life it would be virtually impossible for her to consider that an unseen and unknown friend like God could care for a person he had never physically met, at least in her eyes, and is apparently unknown to her. Hocking believes this lack of trust can be overcome through three main factors that should be indicators of a whether or not a person might be trustworthy.à These three elements, telling the truth, doing what is right and fair, and being reliable, should provide the standards we measure the trustworthy nature of our friends and family, and Hocking explains how these same three factors can influence the level of trust we might have in God. The Bible illustrates countless examples of where God has proven himself in terms of these three measures of trustworthiness.à Hocking describes God as being ââ¬Å"morally pureâ⬠and therefore it would be impossible for God to lie, to be unfair or be someone that could not be depended on.à Hocking refers to the Old Testament that showed how the people of Israel came to trust in God as they walked through the desert, and the New Testament that supported the fact that God could be counted on as a faithful being and one who is always with us.à If these ideas can be understood by an individual then with the passage of time it would be possible for all of us to trust in the one being that will never let us down. Hockingââ¬â¢s viewpoint on God being an accessible, trustworthy and righteous being, who can have influence on an individual in modern life is not a new concept, but understanding the importance of understanding ourselves so that we may understand God more clearly is not a common idea.à Many religious based Churches strive to create a distance between God and man and use concepts such as manââ¬â¢s inclination to sin on earth and generally be considered unworthy in Godââ¬â¢s eyes as a way to maintain that distance. The fact that this distance between God and ourselves only serves the purpose of the Church as a governing body, rather than the individual is often overlooked by many theologians, but Hocking, despite his own religious affiliations, seeks to strip away the negative perceptions that the Church has upheld about man and God throughout the ages and instead paves the way for a life that can be had by any individual who could understand that God can be a friend in every sense of the word. The one stumbling block to this level of understanding is the level of mistrust that is perpetuated in modern society between individuals and groups.à The central premise of Hockingââ¬â¢s book is that to know God we have to know ourselves; to understand God we have to understand ourselves as individuals and to trust in God, we need to trust in others and ourselves.à Stripped of religious hype and forewarnings of doom and gloom that is often manifested by Church groups worldwide, Hockingââ¬â¢s book shows us that it is possible to have a relationship with our Lord, and that this relationship can be based on trust, regardless of the actions of others in our lives.

Sun Hydraulics Essay - 1623 Words
Sun Hydraulics: Leading in Tough Times Case Study Executive Summary Sun Hydraulics, an industry leader of hydraulic valves and manifolds, has seen steady growth over the past eight years. It has been a profitable company throughout the years with varying return on sales. Presently Sun is constrained by declining sales and high labor costs heading into the present recession. The horizontal corporate structure has proven ineffective in ridding itself of low performing employees that are weighing down the company and thus decreasing profitability. It is time for Allen Carlson, president and CEO of Sun Hydraulics Corporation, to address the employees and shareholders of his decision on how Sun plans to deal with labor and profitsâ⬠¦show more contentâ⬠¦The organization is multi-functional, created in Koskiââ¬â¢s vision of ââ¬Å"horizontal managementâ⬠, with no job titles, no hierarchy, no departments, no budgets, no direct sales channels, etc. The employeeââ¬â¢s feel strongly about this structure, as Chairman Cly de Nixon put it, ââ¬Å"Sunââ¬â¢s unstructured environment is the key to our quality.â⬠This unique approach created an active exchange of information among engineering, manufacturing, marketing, and commerce. This horizontal structure does have a downfall, unproductive workers can hide or simply do what they want and choose not to cooperate. Overall the structure seems to work for Sun, and employees genuinely are empowered to work for the greater good of the company. Financially speaking Sun Hydraulics has seen measure growth in sales from 1996 through 2000. Their revenues have grown from $47,374,000 to $66,268,000 from 1996 to 2000 respectively, but I was disappointed in Sunââ¬â¢s fluctuating profitability during this same time, seemingly caused by continually growing labor cost. As a percent of sales, profitability fluctuated from (1%) in 1996 to a high of 7% in 1998.
