  MATH 4321             INFORMATION SHEET FOR TEST THREE         SPRING 2011


  * Test 3 will be in class on Thurs Mar 31.  Test 3 will last 60 minutes.
    You will have approximately 15 minutes before the test starts to ask me any 
    last-minute questions you might have.
    (Note that 11:00-1:30 pm on Fri May 13 is the new time slot for our Final 
    Exam.)
  
  * The relevant sections for the test are Sections (18-20, 21-24, 26), 27, 29.
  . The homework for that material is posted online at my website 
    https://vancliff.utasites.cloud/T/S11/hwk4321.html . 
    You should also look over Tests 1 & 2 and their solution sheets.
  
  * My office hours are Tues/Thurs 3:20-3:50 pm & 5:20-5:50 pm. In addition, 
    some class time before the test starts will be available for asking me 
    questions.  Ph: 817-272-3932, e-mail: vancliff@uta.edu .
  
  * You should learn definitions such as ring, subring, division ring, field,
    unit, zero divisor, integral domain, homomorphism, isomorphism, field of
    quotients, polynomial, zero of a polynomial, (ir)reducible polynomial,  
    ideal, left/right ideal, prime ideal, maximal ideal.  You should be 
    ready to present examples like those occurring in the homework, and be 
    able to show that a subset of a ring is a subring or a left/right/2-sided
    ideal.  Moreover, any question in the homework or on Tests 1 and/or 2 
    are game for the test.
    
  * Only calculators specified on the first-day handout will be permitted in 
    the test.  If you bring one, make sure the batteries are working. Also 
    bring some form of photo ID.
  
  * Try to keep your eyes on your own work during the test.
  
  * If you wish to leave the room during the test, you should ask permission 
    first & turn in your test to me. Only in exceptional circumstances will 
    I let you continue the test should you return. (So it is better to be 
    3 minutes late to the test, rather than ask to go to the bathroom during 
    the test.) If you finish early but prefer to stay in the room, then you 
    should NOT get out any work, book nor item, no matter what the subject 
    matter is, without first checking with me.  Should you wish to leave 
    the test early, then you may.
  
  * It is your responsibility to be on time.
  
  * I plan to return the graded test to you on Tues April 5 with a solution 
    sheet.
