Around in circles...with groups!

Don't forget that if you get stuck you can always pick up an old final exam and do some studying. The links are on the right...and ask some questions by commenting below.

An Icy Pre-Calc Class

Sorry this is a bit late but I thought I'd post a few of the words we had on Thursday.

Circles Everywhere...

Today in Pre-Calc we took a look at Arcs and their corresponding central and inscribed angles. We also spent some time looking at Cyclic Quadrilaterals. The language sounds pretty tough...but the math isn't too bad. I also mentioned that we'll be quizzing Lesson 2 tomorrow. Good luck with the studying.

Some circle stuff for you

Here are the slides for the last couple of classes. Please do your best to have lesson 2 finished for tomorrow.



...and today's slides...

Absolutly Rational Equations

Today we reviewed a how to solve an equation containing radical expressions. It seemed to me that the homework must have gone well since you only asked how to solve the hardest question.

Our topic today was how to solve equations containing absolute values and rationals (fractions). Be sure to post any questions you may have below. Tomorrow will be a review of our work in module 3, with the test being on Friday. For those you who will be away, please make sure to make arrangements with me to write your test at noon or on spare Monday or Tuesday.

Logarithmic Equations (and issues of world power)

Today we discussed how to use logarithms to solve for x when it appears as an exponent in an equation. We also looked at some equations which had x as an argument of the logarithm function. Then we took a quick moment and sidetracked ourselves with discussions of the Cold War, and speculated as to why Japan has never attempted to rebuild it's military. After our curiousity for discussion was satisfied we worked on lesson 7. Please keep in mind that tomorrow will be review day for Module 4; we'll start Module 5 on Thursday and Test Module 4 on Friday. Have a great week. Be sure to post your questions below.

Math 9...Isn't this the GREATEST?

Today's notes are below. As spring wears on please try to keep up the homework and study as it pays off when the tests roll around. We still have half a semester to go!

Some extra explainations and practice can be found HERE

Radical Equations

The slides from today...please post your questions below when they come up. We'll be testing on Friday so for those away you will need to write Monday or Tuesday at noon.

A little Sine Curve help...

Thanks for the question...hope this helps.
