Project #1 -- Landscape Architecture



Assignment

Assume you are working for a landscape architecture firm which has been hired by a large company that wishes to redesign the entry way to their headquarters. The centerpiece of the new entry will be a garden, bordered by a smooth wooden frame. The frame must pass through a collection of one hundred specified points. It will be designed in 10 stages, where each stage will produce a segment of the frame that passes through ten of the one hundred points.

Your task is to design the first of the 10 segments by finding a ninth degree polynomial whose graph passes through the ten points:
(0,3),(1,3),(2,-3),(3,5),(4,2),(-1,2),(-2,0),(-3,0),(-4,-1),(-5,1)

and prepare a report for your supervisor delineating your solution.



Mathematics Needed

You will need an understanding of the idea of a basis for a vector space, as well as an understanding of the Lagrange Interpolation Formula (explained on pages 47-49 of your text).


The Report

The report to your supervisor should contain (at least) the following sections:

Introduction and Summary : This section should give a brief account of the subject matter discussed in your report. Someone should be able to read this first section of your work and understand what the problem is and your response to it. You should also provide a brief outline of your method; include only the major ideas, and describe them in generality.

Method : This is the heart of the report, and the most important part of this assignment. In this section you should not only clearly describe what steps you took to solve the problem, you should also strive to explain to the reader why the steps you took were the right ones to take. In other words, offer a concise explanation of what you understand to be the ideas behind the calculations. You may want to give a brief and very clear explanation of the Lagrange Interpolation Formula, where it came from, and how it was used to solve the problem.

Please do not delve into the gory detail of your computations. It's unnecessary to list every step of every process, and doing so is deathly boring for your reader. It is sufficient to say what you did and why, show the key intermediate steps of the calculation, and then show what resulted from your calculation.

Conclusion : This section will probably be very short. It should clearly state the polynomial you found (whose graph passes though the ten given points), and provide a picture of the graph of that polynomial (copied off of your graphing calculator? from computer lab? using calculus I techniques?), and give a satisfying concluding comment to your report.
