The Flight Path From Singapore

Longitude by Dava Sobel was a book that explained in great detail the struggle to find longitude at sea and way it was so necessary. Sobel talked about the tragedies that followed with not finding longitude at sea and then the discoveries and trials that had occurred to find a final solution. Throughout the book, you understand the urgent need to find longitude why it was so hard, and what it really took in order to come to the final discovery. As you read through this paper you will get an understanding of the topics Sobel talked about in her book such as, the shipwrecks and tragedies that occurred without longitude at sea, the two competing methods to find longitude and the man who discovered it.

* Computation of estimated time en route and total fuel requirement for an IFR cross-country flight.

Work through the explanatory material on units of longitude and latitude, finding longitude and latitude, and a bit of history (optional).

The R2 value determines how close the data is to the function (Penn State). The

The purpose of this experiment was to create a model that showed the motion of a spinning body and to test the accuracy of said model. The model was created by calculating the measurements of the orbital period of a stopping mass for six varying mass ratios and then comparing them to the model equation derived from the equation for centripetal force. The primary results of the lab were in agreement with the predicted values, therefore our degree of confidence in our data was high.

If they do not, but are within the acceptable margin of error of ±20√4=±40’’, each angle is corrected to create a sum of 360˚. For this project, the angles added to 360˚ 00’ 10’’. After each angle is corrected, angle 412 is 78˚31’03’’, angle 123 is 99˚01’23’’, angle 234 is 92˚32’21’’, and angle 341 is 89˚53’13’’. After using the Total Station, the Auto level is used to measure the elevations of each point. The known elevation outside of Powell is 380’. The Auto level is placed between each point to measure the backsight and foresight. Once all the points are measured, all the backsights and foresights can be measured with the difference taken to find the error. With this project, the error was -0.128’. Next, the pacing between each point must be taken to find the correction for each elevation with the equation, (distance from known elevation/total level network distance) X total error. The total pacing for the project is 235 steps with a pace of 2.31 feet per step. After the corrections, point 4 is 379.384’, point 3 is 378.182’, point 2 is 379.093’, and point 1 is 379.645’. A transit is used to find the true north from the magnetic

His model said that the planets moved not in circles around the sun, but in ellipses and the mathematics was proved using three laws:

(between June 20th and June 22nd) the Greek Astronomer, Eratosthenes had heard of a famous well in a Egyptian City called Syene (now known as Aswan) located around the Nile River. He knew that every year on the solstice, there was no shadow on the bottom of well but instead the rays of sunlight reflected back, and not on the sides of the well as on other days. He came to a conclusion that the sun was directly overhead in Syene at noon every year. He knew that in his hometown Alexindra, the sun was never directly above him even on the solstice. He assembled a pole in Alexindra to study and calculate the shadows position eventually proving that no sun was directly above but faintly south. Knowing that the earth was curved and knowing the distance between the two cities, Syene and Alexandra he calculated the planets circumference by doing simple geometry. “Eratosthenes could measure the angle of the Sun’s rays off the vertical by dividing the length of the leg opposite the angle (the length of the shadow) by the leg adjacent to the angle (the height of the pole). This gave him an angle of 7.12 degrees. He knew that the circumference of Earth constituted a circle of 360 degrees, so 7.12 (or 7.2, to divide 360 evenly by 50) degrees would be about one-fiftieth of the circumference. He also knew the approximate distance between Alexandria and Syene, so he could set up this

In the poem “Singapore” by Mary Oliver, there is a very important lesson of social acceptance. The poet speaks of encountering a woman in an airport bathroom stall, cleaning an ashtray in the toilet, and the disgust that she first feels towards this woman and her job. The speaker does however, express that she moves past the judgment that she first feels towards the woman in the stall. She imagines parts of nature and wishes to put the woman in a beautiful place in life. In this poem, the poet uses imagery, connotation, metaphor and symbolism to describe what she is really seeing compared to what she is imagining and would like to see.

Anyone who has ever encountered a circle in math class has faced the issue of finding the circumference and area, or both, of that circle. Additionally, anyone who has attempted to accomplish that task has come into contact with Pi, denoted by the Greek letter π. Pi, pronounced “pie,” represents the ratio of the circumference of a circle to its diameter and has a numerical value of 3.14159… Simple enough. Now, we are introduced to τ, or “tau”, which connects the circumference of a circle to its radius, r. While pi is supported by its historical traditions, “tauists,” as they call themselves, are progressively speaking up in favor of tau. In the battle of pi vs. tau, centuries of practice of pi, a clear understanding of the concepts, and the sheer simplicity of each value lie at stake. I argue that there is absolutely nothing wrong with using either pi or tau; instead, we should just use them as we find most convenient.

This essay examines the question: How does GPS rely on geometry and trigonometry now that there are satellites? Has the function of geometry and trigonometry in triangulation and navigation changed since satellites were

Airline industry is a growing and a challenging industry across the globe and it is becoming more competitive on quality, pricing and most prominently safety in the contemporary world.

The project requires the student to carry out a research, analysis and discussion on how a Singapore listed company can access to the country’s financial system and how it benefits the company in achieving its business objective. The research will cover the various types of financial services offered by financial intermediaries whom the corporation can access to.
