Here are step-by-step solutions for some of the completing-the-square problems on the conic sections review:

And in case you need a blank copy of the review, here it is (again):

Some of you guys need help with these completing-the-square problems:

For the next two blocks, we will be going over partial fraction decomposition.  Here is the assignment for this section:

Here are the class notes (along with my writing) from Friday, April 11 (if they help):

Class Notes: Partial Fractions (April 11 2008)

 

Since this section is not in our textbook, here are a few links to websites that have some reference info, should you need it: 

• Paul's Online Notes: Partial Fractions [pdf version] 
  
• PurpleMath.com - Partial Fraction Decomposition: General Techniques
• Wikipedia.org - Partial Fractions
• NCSU Math and Physics Help Page - Partial Fractions
• Partial Fractions Decomposition

And... last but not least... here's the link to a nice page that will decompose most partial fractions for you:

• QuickMath Partial Fractions Solutions

This is it!  The stretch run~  Here's the syllabus/homework schedule for the final six weeks of the school year:

TAGPreAP Alg II 6th six weeks syllabus 0708.pdf

Please be advised that we are continuing with the B-day-first schedule through all of April and the first week of May.  However, starting with the May 12-13 Chapter 12 test, we are returning to the traditional A-day-first schedule for the rest of the academic year.

update (4/5): there was a typo in the "Extra Practice" worksheet, #10 (the vertices and foci were reversed, and the problem was basically impossible).  This has now been fixed, so please check the link for the correct numbers/answer.

update (4/8): found one more type, in the solution to #9 on the "Extra Practice".  The numerator should read "(y - 7)^2", instead of "(y - 8)^2".

Here is the review for the Chapter 10 test next week:

• TAG-PreAP Chapter 10 Review.pdf | selected step-by-step solutions
• Extra Practice (optional).pdf | selected step-by-step solutions

The Chapter 10 Exam (Conic Sections) is still a few weeks away (~April 23/24), but is one of the most difficult of the course.  To help prepare for this test, we are posting the review a bit earlier than normal:

Algebra II Chapter 10 Review (pdf) | Review Solutions (pdf)

The main links are in Word format, but the pdf links are available as well (the graphs seem to print out a little nicer in Word, but if you have trouble getting the .doc to work right, try the PDFs).

This is it!  We're down to the final six weeks of the year (with TAKS testing sandwiched in the middle).  Here is the syllabus/homework schedule:

Project Due Date: April 17/18, 2008

Here's a blank version of the project handout:  Unicron 2008 blank.pdf

Each group has a different letter at the bottom, which corresponds to different values for aphelion and parahelion; here are those numbers:  

Group	Parahelion	Aphelion
a	36.4	144.6
b	27.4	184.6
c	76.4	545.6
d	28.4	442.6
e	96.4	785.6
f	117.6	426.4
