  MATH 4321             INFORMATION SHEET FOR TEST FOUR         SPRING 2011


  * Test 4 will be in class on Thurs April 28.  Test 4 will last 60 minutes.
    You will have approximately 15 minutes before the test starts to ask me any 
    last-minute questions you might have & also some time on Tues Ap 26 to ask
    some questions.
  
  * The relevant sections for the test are Sections (18-20, 21-24, 26, 27, 29),
    30, 31, 33, 48-51. 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 & 3 & their solution sheets.
  
  * My office hours are Tues/Thurs 3:20-3:50 pm & 5:20-5:50 pm. In addition, 
    some class time on Tues Ap 26 and on Th Ap 28 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, kernel, algebraic, 
    transcendental, finite extension, algebraic closure, algebraically closed,
    (primitive) n'th root of unity, splitting field, index, separable extension, 
    etc.  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.  You should know the statement of any theorem 
    that has a title.  Moreover, any question in the homework or on Tests 1-3 
    is 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 May 3 with a solution 
    sheet. However, we will go over the test on Th May 5 (not May 3).
