Some of the ones that I will cover in this portfolio are the Trapezoidal Rule and the Simpson 1/3 Rule. I will explain how some of these algorithms are used in relation to the numerical integration. Trapezoidal Rule The trapezoidal rule is used to approximate the area under a curve. The approximation uses the area of the trapezoid,h/2(p+q), to find area where the …show more content…
The fact that an infinitesimal number of trapezoids can give you the area under any curve it makes it an important concept. Understanding the Trapezoidal Rule will make understanding integration much easier. The Trapezoidal Rule has many applications in real word problem solving. It is used to weather forecasting and determining how much rainfall is going to fall in a certain part of town. It is a rough estimation of the amount of rainfall. Simpson’s Rule The Simpson Rule is used to approximate the area under a curve. This time instead of using trapezoids to approximate the area under the curve, we use parabolas. The parabolas will help us get a more precise approximation of the area under the curve because we will not have the void space that was caused by trapezoid. The Trapezoidal Rule was the approximated using a first order polynomial were as the Simpson Rule is approximated using a second order polynomial. The formal for the Simpson’s Rule would go as …show more content…
The Newton-Raphson method uses the same principles of the Fixed-Point Iteration with respects that it starts with an initial approximation and then the sequence is generated through iterations from the initial base point. The general form of the function looks as follows: g(x) =x-f(x)/(f^' (x) ) , where the sequence is generated by p_n =g(p_(n-1)) This function will replace the f by the tangent that was estimate by pn value. The function finds the upper and the lower limit and interpolates where the point in between will fall. The root of the equation will be given by this number. Figure 6 shows how the interpolation of the middle value is found by means of the tangent line. The tangent line, in red, is fixed at a point and uses the upper and lower limits to find a single iteration. The Newton-Raphson Method has many applications in approximating the root. When comparing the Newton-Raphson Method with the Fixed-Point Iteration, the best to use would be the Newton-Raphson Method because it will be able to iterate through any function a lot faster. Using the same function, e-x, the Newton-Raphson Method would be able to find the root within 8 iterations while the Fixed-Point Iteration would take 20 iterations to get to same

The population of the world is growing extremely fast. Eventually there is going to be overpopulation and resources are going to run out if something is not done. We know earth is overpopulated and that a control over population can be made or at least something can be done so there is not a catastrophe. Population growth can be determined using exponentials which directly relate to derivatives. This is a tool that can be very helpful for anthropologist and sociologists in the world (which have nothing to do with mathematics). Not only to know population numbers in ten or twenty years but to have control over other things. For example will there be enough food for five billion people in the world, will there be enough mineral supply for five billion people in the world or will there be enough fuel supply for five billion people in the world. Many of those types of investigations can be determined with the application of derivatives.
Newton on the other had would not allow himself to be usurped by stating that “second inventors have no right. Whether Mr Leibniz found the Method by himself or not is not the Question… We take the proper question to be,… who was the first inventor of the method." In addition, he continued on by stating that "to take away the Right of the first inventor, and divide it between him and that other, would be an Act of Injustice."
Calculus, the mathematical study of change, can be separated into two departments: differential calculus, and integral calculus. Both are concerned with infinite sequences and series to define a limit. In order to produce this study, inventors and innovators throughout history have been present and necessary. The ancient Greeks, Indians, and Enlightenment thinkers developed the basic elements of calculus by forming ideas and theories, but it was not until the late 17th century that the theories and concepts were being specified. Originally called infinitesimal calculus, meaning to create a solution for calculating objects smaller than any feasible measurement previously known through the use of symbolic manipulation of expressions. Generally accepted, Isaac Newton and Gottfried Leibniz were recognized as the two major inventors and innovators of calculus, but the controversy appeared when both wanted sole credit of the invention of calculus. This paper will display the typical reason of why Newton was the inventor of calculus and Leibniz was the innovator, while both contributed an immense amount of knowledge to the system.
...hat it could also be used to show measurements, be used in science, and that it could be used to ride in things such as hot air balloons. It could be used to find measurements because you could be trying to fill up the balloon just to see how tall or how wide it can get, and then measure it. It could also be used in science for that reason, and if you were testing the acidity in something, and having it fill up with something other than air or helium.
Through out my life, nothing has ever fascinated me like the application of mathematics in real life situations. In real life, the application of mathematics acts as a foundation from which economics progresses as it offers a person with different knowledge on how they are supposed to carry out different life applications. Mathematics offers an individual with the right differentiation skills that are highly required in making different calculations of elasticity coefficients that are applied in different sectors of the world. My greatest inspiration in the application of mathematics in real life experience has been “ The Pleasure of Counting”. By T. W. Korner’s. Through the work of Korner, I have been enabled to increase the rate to which I apply the mathematical knowledge that I have acquired over the years to real world situations. Some of the areas that I have increasingly applied my mathematical knowledge includes in the economics as well as in the field of finance. The application of mathematics in this filed has contributed towards my critical thinking and analytical skills progress.
Ever wonder how scientists figure out how long it takes for the radiation from a nuclear weapon to decay? This dilemma can be solved by calculus, which helps determine the rate of decay of the radioactive material. Calculus can aid people in many everyday situations, such as deciding how much fencing is needed to encompass a designated area. Finding how gravity affects certain objects is how calculus aids people who study Physics. Mechanics find calculus useful to determine rates of flow of fluids in a car. Numerous developments in mathematics by Ancient Greeks to Europeans led to the discovery of integral calculus, which is still expanding. The first mathematicians came from Egypt, where they discovered the rule for the volume of a pyramid and approximation of the area of a circle. Later, Greeks made tremendous discoveries. Archimedes extended the method of inscribed and circumscribed figures by means of heuristic, which are rules that are specific to a given problem and can therefore help guide the search. These arguments involved parallel slices of figures and the laws of the lever, the idea of a surface as made up of lines. Finding areas and volumes of figures by using conic section (a circle, point, hyperbola, etc.) and weighing infinitely thin slices of figures, an idea used in integral calculus today was also a discovery of Archimedes. One of Archimedes's major crucial discoveries for integral calculus was a limit that allows the "slices" of a figure to be infinitely thin. Another Greek, Euclid, developed ideas supporting the theory of calculus, but the logic basis was not sustained since infinity and continuity weren't established yet (Boyer 47). His one mistake in finding a definite integral was that it is not found by the sums of an infinite number of points, lines, or surfaces but by the limit of an infinite sequence (Boyer 47). These early discoveries aided Newton and Leibniz in the development of calculus. In the 17th century, people from all over Europe made numerous mathematics discoveries in the integral calculus field. Johannes Kepler "anticipat(ed) results found… in the integral calculus" (Boyer 109) with his summations. For instance, in his Astronomia nova, he formed a summation similar to integral calculus dealing with sine and cosine. F. B. Cavalieri expanded on Johannes Kepler's work on measuring volumes. Also, he "investigate[d] areas under the curve" ("Calculus (mathematics)") with what he called "indivisible magnitudes.
Mathematics, the language of the universe, is one of the largest fields of study in the world today. With the roots of the math tree beginning in simple mathematics such as, one digit plus one digit, and one digit minus one digit, the tree of mathematics comes together in the more complex field of algebra to form the true base of calculations as the trunk. As we get higher, branches begin to form creating more specialized forms of numerical comprehension and schools of mathematical thought. Some examples of these are the applications into chemistry, economics and computers. Further up the tree we see the crown beginning to form with the introduction of calculus based organization. Calculus, a theoretical school of mathematical thought, had its creation in the middle ages with Newton. The main use of calculus is its application in advanced physics. Mathematics is everywhere because that is where we put them, everywhere. We, humans, represent everything with numbers, which therefore means that we impose mathematics on to the universe.
As it is an extension of another concept, this paper aims first to introduce Pascal’s Triangle and then to apply its properties in deriving each layer of Pascal’s Pyramid. From there, a trinomial principle or theorem is to be formed that will govern the coefficients. For its use in trinomial expansion, the author also aims to compare using any formulas or sho...
Differential calculus is a subfield of Calculus that focuses on derivates, which are used to describe rates of change that are not constants. The term ‘differential’ comes from the process known as differentiation, which is the process of finding the derivative of a curve. Differential calculus is a major topic covered in calculus. According to Interactive Mathematics, “We use the derivative to determine the maximum and minimum values of particular functions (e.g. cost, strength, amount of material used in a building, profit, loss, etc.).” Not only are derivatives used to determine how to maximize or minimize functions, but they are also used in determining how two related variables are changing over time in relation to each other. Eight different differential rules were established in order to assist with finding the derivative of a function. Those rules include chain rule, the differentiation of the sum and difference of equations, the constant rule, the product rule, the quotient rule, and more. In addition to these differential rules, optimization is an application of differential calculus used today to effectively help with efficiency. Also, partial differentiation and implicit differentiation are subgroups of differential calculus that allow derivatives to be taken to more challenging and difficult formulas. The mean value theorem is applied in differential calculus. This rule basically states that there is at least one tangent line that produces the same slope as the slope made by the endpoints found on a closed interval. Differential calculus began to develop due to Sir Isaac Newton’s biggest problem: navigation at sea. Shipwrecks were frequent all due to the captain being unaware of how the Earth, planets, and stars mov...
