The first Math 11 exam will be held Wednesday, October 22 from 5:30 - 7:30pm in Cook Auditorium.

• The exam covers all material from the beginning of term through Assignment 10.
• The exam is designed so that well prepared students can complete the exam in one hour, however you will be given two hours for the exam which should eliminate time pressure considerations for all students.
• Please arrive by 5:15 to allow ample time to get seated, settled, and exams distributed by 5:30.  The room will be crowded since both sections of math 11 will be present.  To make life easier, please sit with precisely one empty seat between you and your neighbor.
• Naturally, bring writing implements; pens or (sharpened) pencils are fine.  Scrap paper will be attached to each exam; you may not use your own.
• Calculators may be used for numerical work or graphing if you like, but under no circumstances are they to be used in any other way, e.g., to store information, run programs, symbolic manipulation.  They are certainly not required, nor should they be of much use.  Except in trivial cases, answers need not be simplified and more importantly, answers need to be exact.  For example, someone saying the answer to a problem is 1.414213562 instead of the correct answer of sqrt(2) is wrong, and will lose credit accordingly.
• There will be two Question and Answer sessions on Tuesday (October 21), starting at 7pm.  Arkowitz's Q &A will be in 107 Steele, and Shemanske's will be in 3 Rockefeller.
• Sample questions are available via the Math 11 home page.

• Monday:  (Assignment 24)
• Study:  Chapter 10, section 9
• Do page 812:  1, 7, 10, 13, 21, plus the following problem:
• You have just been hired by Texas Instruments to help build a new calculator.  Your job is to create the sine and cosine algorithms, and your mission is to able to approximate the value of sine and cosine for any number a user enters with an error of < 10^(-14).  Fortunately, you still have your class notes from Math 11 in which you learned how to use Taylor polynomials to approximate both of these functions.
• First, give an argument which convinces a learned reader that you really need only be able to approximate the values of sine and cosine for x in [-pi/4, pi/4], given that your algorithm can also include various trigonometric identities and properties. For example, explain how the property sin(x) = sin(x + 2*pi), allows you to simplify your task of allowing for any number to be entered by the user, to simply knowing the values of sine and cosine for x in [-pi,pi].  Now continue on your own.  After all, that's why TI is paying you the big bucks.
• Next determine what degree Taylor polynomial is required to guarantee an error of less than 10^(-14) for sin(x) on the interval [-pi/4, pi/4].
