Survey

https://docs.google.com/a/oconeeschools.org/spreadsheet/viewform?fromEmail=true&formkey=dHB1WmhpeVlMNkRBVFdfTlFfUlVRYkE6MQ

I went to this training the school held for us on Thursday covering all kinds of things about Google, and it was pretty cool.  One thing they showed us was how easy it is to create forms or surveys like this.  It was suggested that homework could be administered or checked this way ... not a bad idea.

So, I wanted to give it a test run.  I hope clicking on the above link will work.  Please do so and answer the very easy questions.  If you did, there is incentive at the end.  The incentive is only good through Tuesday morning, i.e., when I get to work on Tuesday, October 2, I will look at the final answers and only those people will have a chance for the incentive.  {Makes you want to look, doesn't it?}

Trig Identities

Math 4 students have a test on Tuesday, September 25, over trigonometric identities and the Sum and Difference formulas.

I'm compiling a list of websites that might be helpful in getting extra practice for verifying identities.

As always, if you type in the name of the subject we are studying, the internet is full of incredible resources of all different types to help you in your mathematical journey!

http://www.purplemath.com/modules/proving.htm
This is a great site with several good examples and explanations into each step of the problem (Purplemath.com is a fantastic web site for looking up math stuff in general!)

http://www.intmath.com/analytic-trigonometry/1-trigonometric-identities.php
Scroll to the bottom to see a few exercises and examples with buttons to press to see how the authors solved them (remember: you may do it a different way than someone else, but both solutions may be legitimate)

http://www.math.siu.edu/previews/109/109_Topic8.pdf
There are some good explanations, but scroll to pages 4 and 9 (especially 9) and you'll find some problems to work (along with solutions on another page)

http://worksheets.tutorvista.com/proving-trigonometric-identities-worksheet.html
This page has lots of multiple choice problems where you can check your answers.

With any of these, if you are stumped or don't understand the solution, email me (mlewis@oconeeschools.org) or send me a Tweet (@MrLewisNOHS) and I will be glad to help you.  I will be at the football game Friday night and in and out most of the day Saturday, but I will try to get back to you as soon as I can (Twitter may be the best way to get me!).

New Schedule for Computer Science Club

We decided this morning to move the Computer Science Club to every other Thursday afternoon.  The Chess Board is also meeting in Room # 2209 Thursdays after school, so there should be a fun group of people to work together.

Details and the next meeting date can be found on the Computer Science Club page.

Math League

Check out the Math Team page for details about the first Math League Contest Test.

Math Team Meetings 9/12-13

Check the Math Team page for a summary of what happened in this week's meetings.  Next meetings are September 26 & 27.

Old Blog Posts

With help from the Oconee Technology people, I got most of my old posts from last year's blog on to this one, so there will be less recreating of the wheel (so to speak).  You may find something from last year interesting, or not.  Anyway, I will work on cleaning this page up and make several pages dedicated specifically to the club or class you are interested in.

Let me know what you think or suggestions you'd like to make.  Thanks!

Math 4 Test # 2 Review Questions

We discussed the "Why?" questions that will be on the test.  Think about what they are, then search for them.  Google and Wolfram Alpha are good places to search from.

For example, type "domain of arcsin" into Google and a lot of great pages with a wide range of explanations, from very simple to very complex, come up.

Math IV Test # 2

Tomorrow (Thursday, September 5) is when we will have our second test in Math IV.  Since this is our second test, the weight of this test will affect our grade a good bit, so I know most of us would like to see some improvement.  We did a pretty extensive review in class today and students made some great-looking review booklets Tuesday.

Here are a couple of websites with some extra problems and some more explanation for review.  Check the previous post about Helpful Math Websites for a trig function grapher.

(This is a nice presentation of inverse trig functions.  There's some great problems all the way at the end, so stay with it)

Math Team 1st Meeting

I will make pages for each of my classes and for the different clubs I'm working with.  This morning was the first meeting for the Math Team ... and only one student was there.  However, we are meeting this afternoon, too.  If you are unable to attend either meeting, please see more or send me an email or other form of communication and let me get so info to you and from you.

Thanks!

Helpful Math Websites

I will try to share some of the nice websites that I use and come across in this blog.  I will make a page called “Helpful Math Websites” and it will be an ongoing list of pages that I think are neat.  Feel free to email me if any links are busted or if you want help navigating the sites.

Lewis Math Class Blog 2.0

New school year, new blog format!

I had a blog last year, but the district is not supporting the format anymore, so I am trying to move on.  I've spent some time looking at Moodle, but I just have not made it work in my head.  So... here comes the blog on Blogger (from Google).

I hope you will find this useful, and I plan to put a lot of stuff on here.  Your comments will be very helpful.
Thanks!
