Algebra I due Friday:

Page 420 to 423, alternative odds.

Pre-Calc - Section 11.5 odds

Ax2 + Bxy + Cy2 + Dx +Ey +F = 0 General Form
Case where B=0, (A≠C = 0)

- If AC=0, we have parabola

- If AC>0, we have an ellipse
- or circle if A=C

- If AC<0, we have a hyperbola
(General Case)

If B2 - 4AC = 0 -- a parabola

If B2 - 4AC < 0 -- an ellipse or circle

If B2 - 4AC >0 -- a hyperbola

cot(2θ) = A - C
B

Procedure:

1. Determine rotation of axes (θ)

2. Sketch new axes.

3. Algebraically transform General Form into standard form.

4. Graph conic on new axes using standard methods.

Writing across the Curriculum Paper - Spring

Due date: April 20th, 2009

This paper is worth 100 points in your math class, plus it is also graded for Writing Across the Curriculum by Mrs. Frank.

Algebra I Topic: “If I lived in a world without mathematics…” What would such a world be like? How would you live? What changes would there be? How would it affect your understanding of spiritual things? 2 to 5 pages, double-spaced and typed.

Trigonometry Topic: The Horatio Hornblower novels of Forester, as well as the Master and Commander novels of Patrick O’Brien used trigonometry in navigation. George Washington was a well-known surveyor before becoming a politician, the steam engine was ultimately based upon motion described by sin functions, and the Space Program would not have happened without trigonometry. Explain how trigonometry will affect your life and behavior either directly or indirectly (perhaps by using a detailed metaphor, spiritual or otherwise.) 3 to 6 pages, double-spaced and typed.

Pre-Calculus Topic: If you were a function, what would it be and why? (Get creative.) Be sure to explain your choice of variables, constants, and mathematical operations, and how they relate to you and your life. 3 to 6 pages, double-spaced and typed.

Calculus Topic: In the “snowflake” parametric curve, we found that an infinitely long and infinitely complex perimeter could be packed into a finite-sized circular region. The Mandelbrot set also demonstrates this with beauty. How does this concept – infinite complexity in a finite region - change your perspective on your life, the Universe, and your spiritual understanding? Feel free to expand the concept as needed. 4 to 8 pages, double-spaced and typed.

Get plenty of rest tonight!

Test Review - Algebra I

Before you leave:
Make a list of the things you need to know for the test as a group

Homework

Chapter Reivew - page 387-389 ALL
Chapter Test - Page 390 - ALL

Test is Thursday

National Honor Society Calculus and Pre-Calculus students are in Mrs. Wildt's room by 7:40 AM every morning if you need tutoring or homework help.

Pre-Calculus

Test on Thursday
Chapter Review on Wednesday
Complete the Practice Quiz for review on Wednesday.

Trig Section P-9

Inverse Functions

If f(g(x)) = x and g(f(x)) = x for all x's in the appropriate domains, then g(x) is the INVERSE of f(x)

g(x) = f -1(x)

f(f -1(x) = x and f -1(f(x) = x

domain f(x) = range f -1(x) and
range f(x) = domain f -1(x)

Finding an inverse algebraically

1) Replace f(x) by y
2) Swap all x's and y's
3) Solve for y
4) Replace y with f -1(x)

Test: is the range of f(x) = domain of
f -1(x) and vice versa?

Do all homework divisible by 3

Tips for Learning Algebra I

There are several layers of learning. First, you "get" the concept. Next, you learn the procedure. Third, you practice the procedure until you consistently get the right answers to the problems.

But what if you're one of those students that does all of this, but forgets the procedure on a test?

Take it to the next level....

Every night, select five problems from LAST week's lessons. Work those problems also. This helps you remember how to work the problems.

You see, your mind is very efficient at forgetting things that don't appear to be important. And in the ancient world, very few people needed Algebra. So our minds are designed to forget math. The way to remember something is to remember it repeatedly over the course of several days and weeks. Then, you won't forget it for years!

GRADE CARDS - FIRST SEMESTER

If your son or daughter received an "I" on the gradecard, or a code "18", this means that I am still missing work. I will accept this work up to end of day Wednesday, Feb 4. and make changes which will be reflected in the permanent grade. The grades on the grade card reflect a "0" for missing work.

Feel free to email me or otherwise contact me at school. My email prefix is bboley followed by @pchs1.com.

If you want to have a conference, I am available during school hours at 2:10 until 3 PM, and then immediately after school (let me know that you are coming.)

Welcome back!
