...The whole idea of the “Cartesian Circle” is an interesting case to look it. The main premise is that Descartes presupposes something, such as the existence of the all-perfect God, to prove that the premise is true, the existence of the all-perfect God. Many critics argue that he creates a circular argument, hence “Cartesian Circle” and with a circular argument nothing concrete is really being proven. According to the Stanford Encyclopedia of Philosophy, Descartes argument can be broken down into two main steps (Newman). The first step sheds light in the Third Meditations, where Descartes makes arguments for the existence of an all-perfect God. The second step is where Descartes takes the now established premise to argue that the all-perfect God exists. In short, Descartes is arguing that since he thinks, he exists and since he exists, an all-perfect God exists. Finally, since the all-perfect God exists, he thinks. This creates a circular argument according to his critics. One of the objections to Descartes is in reference to the atheists. Descartes argument would lead us to believe that since atheists do not believe in the existence of the all-perfect God. The example used is the sum of the angles of a triangle equating to the angles of two right angles (Second Objections, DSW, p. 139). The critic would argue that under Descartes philosophy atheists, by default do not believe in the higher being, thus would not be able to have the knowledge to comprehend the idea that two right...

...1. Scan converting a circle Circle is one of the most widely used shape in drawing pictures and graphs and in computer graphics, various procedures are developed to draw complete circles or any portion of it such as arcs and sectors. A circle is such a geometric shape that is defined by a center position and a fixed distance from the center which is called radius. It is drawn by combining all the points that are at a fixed distance from the center. Scan converting a circle requires each point on the circumference of the circle to be illuminated. Various algorithms and techniques are employed in computer graphics to scan convert a circle that uses equation of circle. The Polynomial equation of the circle in Cartesian coordinates whose center...

...Introduction This tutorial is designed to show you how all of the AutoCAD Draw commands work. If you just need information quickly, use the QuickFind toolbar below to go straight to the command you want or select a topic from the contents list above. Not all of the Draw commands that appear on the Draw toolbar are covered in this tutorial. Blocks, Hatch and Text for example are all tutorial topics in their own right! |[pic] |[pic] | |Pull-down |Draw[pic]Line | |Keyboard |LINE |short-cut |L | With the Line command you can draw a simple line from one point to another. When you pick the first point and move the cross-hairs to the location of the second point you will see a rubber band line which shows you where the line will be drawn when the second point is picked. Line objects have two ends (the first point and the last point). You can continue picking points and AutoCAD will draw a straight line between each picked point and the previous point. Each line segment drawn is a separate object and can be moved or erased as required. To end this command, just hit the [pic]key on the keyboard. Command Sequence Command: LINE Specify first point: (pick P1) Specify next point or [Undo]: (pick P2) Specify next point or [Undo]: [pic](to end) You can also draw lines by entering the co-ordinates of their end points at the command prompt rather than picking their position from the screen...

...sixty proofs of the Butterfly Theorem, including the synthetical proof, area proof, trigonometric proof, analytic proof and so on. And based on the extension and evolution of the Butterfly Theorem, people can get various interesting and beautiful results. The definition of the Butterfly Theorem is here below: “Let M be the midpoint of a chord PQ of a circle, through which two other chords AB and CD are drawn; AD cuts PQ at X and BC cuts PQ at Y. Prove that M is also the midpoint of XY.” (Bogomolny) This is the most accurate definition currently. However, Butterfly Theorem has experienced some changes and developments. The first statement of the Butterfly Theorem appeared in the early 17th century. In 1803, a Scottish mathematician, William Wallace, posed the problem of the Butterfly Theorem in the magazine The Gentlemen’s Mathematical Companion. Here is the original problem below: “If from any two points B, E, in the circumference of a circle given in magnitude and position two right lines BCA, EDA, be drawn cutting the circle in C and D, and meeting in A; and from the point of intersection A to the centre of the circle AO be drawn, and the points E, C; B, D joined, and produced to meet an indefinite perpendicular erected at A on AO; then will FA be always equal AF. Required the demonstration?”(Bogomolny) (Figures of W Wallace’s question) Soon afterwards, there were three solutions published in 1804. And in 1805, William Herschel, a British...

...Worksheet for Week 1: Circles and lines This worksheet is a review of circles and lines, and will give you some practice with algebra and with graphing. Also, this worksheet introduces the idea of “tangent lines” to circles. Later on in Math 124, you’ll learn how to find tangent lines to many other types of curves. 1. Two circles, called C1 and C2 , are graphed below. The center of C1 is at the origin, and the center of C2 is the point in the first quadrant where the line y = x intersects C1 . Suppose C1 has radius 2. C2 touches the x and y axes each in one point. What are the equations of the two circles? y y=x C2 x C1 Worksheet Math 124 Week 1 2. Let C be the circle of radius 5 centered at the origin. The tangent line to C at a point Q is the line through Q that’s perpendicular to the radial line connecting Q to the center. (See picture.) Use this information to find the equations of the tangent lines at P and Q below. y Q P x Note: Later in Math 124, you’ll learn how to find tangent lines to curves that are not circles!

First we need to know the formula (or algorithm) to find the area/ circumfrence of a circle. Step 6) We need to tell the user that we are going to find the area and circumfrence of a circle... so we say: print("\nNow, let's find the circumference and area of a circle...") Step 7) Next we need to get the user to input the radius of the circle that they want to find the circumfrence and area for: we need the radius to be entered as a specific type of data called a float (a number with decimals) so we type: rad = float(input("Enter radius: ")) Step 8) Now we need to compute the circumfrence: we now...

...The symbols in each movie 1) The photos in BLOOD SIMPLE are the start of all the misunderstandings. In the past Marty didn’t know anything about the fair of his wife. But after the first few pictures taken by Visser, his anger came out and he started his revenge and got involved in this nightmare. The fake picture of Abby and Ray dead in the bed also misleads Marty. When Marty was about to give Visser the money, Visser shot Marty. And Visser throw Abby’s gun in the room to create a misleading scene. These things start with the fake picture. And as Visser says, “life is very uncertain and something can always go wrong.” The appearance of the fake pictures is the moment that life goes wrong for Marty. Marty’s life was totally changed because of this fake picture. He wanted to kill Ray and his unfaithful wife, but instead he is the first one who was shot and got buried alive. Because of the photos, a series of misunderstandings begin. Ray thought Abby killed Marty and Abby thought Visser was Marty and killed him. All the twists start from these photos. Everybody was confused after this. Nobody in the movie truly knows what was happening to everybody. Even Visser, who thinks he knows everything, was also confused at the end. The photos are fake, and this tells us that everything can happen because of money. The photos can be faked, and also the relationship and everything valuable in the world can be faked and changed because of money. The photos triggered the twists and misleading...

...think on what to do with our second half of lives because we cannot put hope that we will still be working in the same organization in twenty years from now. As the saying goes, “Failure to prepare is preparing to fail.” We were taught in class the graph of life; as we are getting older, the options that are available to us are getting smaller, but the responsibilities are getting bigger. So at this young age, we need to grab any chances for the benefit of our future. As the professor said in class, “Don’t get old, alone and broke.” If we did, we might have nothing at all; even family. We do not want to be a burden to ourselves and people around us. Life is about drawing circles. If we have a great life, we will draw a perfect round circle. If we slipped somewhere, the circles drawn might not look like a circle. There are three ways to spend the second half of life. The first is to start a second and different career which is moving from one kind of organization to another. They may stay in the same kind of work, but some move into a different line of work. These people are actually happy with their first job but they need a community as the kids are grown up. They need income too but most...

... Bus The “Bus Topology” is a network setup in which each computer and network device are connected to a single cable. This type of setup is not good for large networks for many reasons. Some reasons are difficulty in troubleshooting individual devices and the entire network, the network can fail if the cable is damaged, and the more devices on the network slows down the entire network. In contrary to larger networks, this set up is perfect for smaller networks, because it requires less cable length and setting up the actual network is easier as well. Ring This network is mostly used in schools and offices, where the networks are smaller. In this setup the devices are connected to each other going in a circle shape, so that each packet must go around the circle until it reaches its destination. Data flows only in one direction at high speeds between the workstations, therefore no requirement for a server needed. In addition, the cost is a bit more expensive to connect the workstation and when a workstation shuts down the entire network will be...

The long strokes of lines and curves in the mirror by her face and around her head display a covering a sense of innocence; before she has known a man intimately. The lines in the lower area of her body in the mirror shows it is still in development as the lines are arched up and not down in a drooping manner as with age. Her body has not set firmly in position so it appears altered in the mirror just like a teenager starting puberty; one breast grows larger than the other. In her conversation with herself she knows her innocence has vanished, and a development is changing her life once again; the baby growing within her. The circles remind me of life.
