Okay....angles associated with circles.   Remember, vertex inside add and take half, vertex outside subtract and take half, vertex on...just take half.  Here is a website with some example problems.

How about simplifying radicals?  If you need help, go here.  If you go there, make sure and check out the second page by clicking the link to "second level" down at the bottom.

Looking for help on complex numbers?  Go here.

Here is a website that might help you with multiplying and dividing complex numbers.  Don't forget to spend some time with angles and segments related to circles.  Remember, vertex inside...add and take half, vertex outside...subtract and take half, vertex on...just take half.  I'll add more in a bit.  Hope the website helps.  This website will be updated repeatedly over the course of the weekend so make sure and check back.

Reviewing for Unit 13

Test for Unit 13 will be on Monday.  Here is a review to start working on.
Test Review

HW for our first day back after snowzilla!  Quiz tomorrow...should be fun!

Live Eagle Cam for when you finish your homework.

Notes for 13.1
We will be starting an investigation of complex numbers now as we work our way towards solving quadratic equations.  Complex numbers are involved in the development of fractals.  They are also used in navigation.  The test over this unit as well as segments and angles related to circles will be next Friday.
