Friday, August 25, 2006
Today, we discussed lesson 8.5

Lesson 8.3

Today, we learned to write and evaluate logarithmic (aka log) functions.
We also learned how to graph the log functions.
Possible warm-up quiz beginning of class Wednesday on 8.1 - 8.3...

Today is "sign up day", the day when all MSHS trig students will create a user ID and Password for our trig blog.

Good Evening,
Well, day 3 is over. I hope all of your new classes are going well. I can already see that the students in both of my trig classes are hard workers who will do their best.

Today in adv. alg./trig, we reviewed lesson 7.2 in the alg. II book. The objective of this lesson is to understand the rules for multiplying and dividing radical expression.

Here are the rules for multiplying radicals:
*If indices match, multiply coefficient times coefficient and radicand times radicand.
*Radicand(s) may be simplified before or after multiplication.

Now, let's review how to divide rational expressions:
*Simplify before rationalizing the denominator.
For example, if you have "the square root of 6x" in the numerator, and "the square root of 2" in the denominator, put one big radical over the fraction and simplify to get the "square root of 3x" as your answer!

**If the numerator is not divisible by the denominator, then you must "rationalize" so that your denominator no longer contains a radical.

Rationalizing examples:
**If your denominator is "the square root of 3x", multiply both numerator and denominator by "the square root of 3x".
***If your denominator is "the cube root of 3x", multiply both numerator and denominator by "the cube root of 3 squared x squared"

Today's 7.2 Assignment:
page 371: 35, 36-54 even; 55-65 odd; 69-75 all; 77-83 odd

Greetings Trig Students
It's Friday Afternoon and we just finished fourth block. I am about to leave for Montgomery (moving a son), but just wanted to let you know I will be the "scribe" who posts a review of today's lesson (7.1). I will do this Sunday when I return.
Enjoy your weekend.
Mrs. S
