Beginning NEXT week, note the following changes in our class schedule:

First of all, there will be no class meeting on Monday, April 2.

Thereafter, we will start a new section each Wednesday, go over homework assignments on Friday, and have quizzes on Monday.   So for example, here is the schedule for the next week and a half:

Mon. 4/2	No class.
Wed. 4/4	Lecture on section 8A
Fri. 4/6	Go over homework from 8A
Mon. 4/9	QUIZ, section 8A
Wed. 4/11	Lecture on section 8B

...etc.

Please email me if you have any questions about this new schedule.

February 23: 
Quiz #4. Solutions to the sample midterm are now available.  Make sure to try to do the midterm on your own first, before looking at the solutions!  (If you read the solutions first, then the sample midterm will be of almost no use to you.)

Mailing List Information.   You may find it convenient to access the class mailing list over the web, rather than just by email.  The URL for the MATH55-9 mailing list is  http://cronkite.temple.edu/archives/math55-9.html.  From this page, you may read all messages sent to the list (sorted by month), post a new message to the list, or change your email settings. 

(NOTE: If you edit your email settings, I ask that you leave the "subscription type" set on "regular," at least until the list becomes much more active than it is now.)

February 2: 
Mailing List Problems.  A few of you mentioned in class that you've had difficulty joining the class mailing list by email.  An alternative may be to go the the list's web page: http://cronkite.temple.edu/archives/math55-9.html.  From this page, click on "Join or Leave the list," and try your luck there. Let me know if you try this, and tell me if it worked for you.

Quiz #2.  The quiz is available on the Quizzes page, along with solutions.  Grades will be posted soon.

January 30: 
MSRC Supplementary Instruction Sessions.
The MSRC  (Math & Science Resources Center) will hold "Supplementary Instruction Session" once per week, on Wednesday, 10:30-12:30, in 102 Curtis Hall.  This is a group tutoring session which you may wish to attend.

Savings Plan Calculator? I'm still trying to find a good one online.  "FinAid" (the site I linked to for their Compound Interest calculator) has one, but it assumes deposits are made at the beginning of each month, rather than at the end (which is the assumption made by our textbook).  So, its results would not match yours.  When I find something more useful, I'll post a link here. Let me know if you find anything!

January 25: 
New Office Hours. Due to a schedule conflict, I've had to reschedule my office hours.  From now on, my office hours will be Tuesday/Thursday, 1:40-3:30 PM.  Please make a note of this change.  (Of course, you may still schedule an appointment if you'd prefer to meet with me at some other time.)

Mailing List. I have set up a mailing list for this class.  To join the mailing list, go to Computer Services' Listserv Page,  click on "II. Subscribing to a list," and follow the instructions given there.  The "listname" is MATH55-9.  If you have any problems signing up for the list, please let me know right away.  Every student is expected to join the mailing list.

You can use the list to discuss lectures, HW, etc., with the rest of the class.  I will use it to alert you to new updates or additions to the class web page, and to disseminate any information or comments which we didn't have time for in class.  Hopefully we can find other productive uses for the mailing list as well.

January 19: 
Section 5A, Compound Interest.  If you'd care for some additional practice at solving compound interest problems, try the following link to the FinAid Compound Interest Calculator.  You can practice solving for A (accumulation) by selecting any values you like for the principal, interest rate and frequency.  Make up your own problems, try to solve them on your own, then use the Compound Interest Calculator to check your result.

Note: on the Calculator page, "Nominal Annual Interest Rate" is the same thing as "Annual Percentage Rate" (APR) in our textbook.

Note: the result is given as a percentage; the total accumulation is equal to the principal times this percentage.  For example, if P=2000 and the "Compounded Rate of Return" is 140%, then the accumulation is 2000*1.4 = 2800.

You can also practice solving for the principal, P, as follows: choose an interest rate, frequency and final amount (accumulation), and solve for P on your own.  Then type into the Calculator your annual interest rate and frequency, and look for the result to be exactly the accumulation amount you originally chose.  (Again, accumulation equals principal times "rate of return.")  If so, you did the problem correctly; if not, something is wrong in your work.

January 17:
Welcome to our class's homepage!  Here is your first assignment: send me email.  (If the preceding link doesn't work, send email to the address: ludwick@math.temple.edu.)  In your email, tell me each of the following:

	Your name
		Include the form you prefer, if applicable: for example, "Mike" instead of "Michael," "Susan" rather than "Sue," etc.  You do not need to include your student ID number.
	Contact Information
		This includes your phone number and your email address (if the address you'd prefer for me to use is different from the "From:" address of your email)
	Major
	Year in College (1st, 2nd, etc.)
	Something interesting about yourself
		Anything you want to say here is fine; what would you like for me to know about you?
	Previous math experience
		Courses taken, good/bad, nice/scary, etc.; say as much or as little as you're comfortable with here.
	Any factors I should know about which may affect your performance in this class
		For example: interscholastic sports, extracurricular activities, disabilities, etc.
	A joke (Keep it clean!)
