Spring 2007 Math 151 Matlab Assignment 3

Description

1. Students will work together in their STEPS teams. In this manner they will:
   
   
   • finish assignments more quickly and cross-check each other's work;
     
     
   • give their TAs a more manageable amount to grade;
     
     
   • build their networking and cooperation skills.
     
     
2. In Chapter 3 of your Matlab lab manual and Chapter 3 of your textbook, do the following problems.
   
   
   • g073x01, g074x07, g076x11, g076x12,
   • s236x84 (also draw curve and tangent line for -1.50 < t < 1.50).
   
   
3. For each problem, you'll work out of the MATLAB Editor. You'll interactively save and run your MATLAB M-file, writing input and output to a diary file. If you have graphics, save your figure files and export them as Encapsulated PostScript. For example, the four files for the last problem are:
   
   
   • s236x84.m: M-file with MATLAB input commands and comments
   • s236x84.txt: diary file with input and output interspersed
   • s236x84.fig: figure file containing graphics
   • s236x84.eps: Encapsulated PostScript printer file
   
   
4. You'll print out the .txt and .eps files via xprint. Do any hand work on ruled notebook paper or engineering green graph paper.
   
   
5. Regarding the figures themselves, interactively edit them. Put on labels; insert text or arrows; change line thicknesses; etc.
   
   
6. This assignment is due Wed-Thu, 14-15/Feb, at the START of computer lab. Be sure to manage your time according to your schedule. Do NOT put things off!
   
   
7. When you finish, you will turn in the documentation of your Matlab work to your TA. Everyone will do this on Wed-Thu, 14-15/Feb (not before), to make things easier for your TA. In this regard, make sure the following information is on a cover sheet.
   
   
   • Spring 2007 Math 151 Matlab Assignment 3
     
     
   • Section 80x, Your Name, Student ID [here x = 1-6]
   
   
8. Various MATLAB videos that you have viewed in advance show how to use xprint to print your diary .txt and graphics .eps files from CalcLab.
   
   

Notes

• There are samples of the types of problems you have to do in Chapter 3 of your lab manual and your lecture handouts. You may also watch the MATLAB 3 streaming videos if you have not already done so: Part A Part B Part C.
  
  
• Do a bit of preliminary hand work for g076x12. You'll find it similar to s068x34, both a homework and MATLAB problem (from MATLAB Assignment 1).
  
  
• For s236x84, the only description of a tangent vector that you've had thusfar (in Section 2.1 of Stewart) is the numerical limit of a secant vector. This will suffice. To effect the needful, make a function M-file named r.m, as shown in the video. For your convenience, here are the script and function M-files from the video. Season to taste; i.e., adapt them to the problem in the assignment. Bon appetit!
  • s236x81.m
  • r.m
  
  
• You may wish to print out intermediate versions of your Matlab code or figures during the next week to discuss with your instructor, TA, or MATLAB help session staff.
