Welcome to Mr. Long’s Math Blog

August 15th, 2014

I use this blog to post lesson plans and homework for my Math Options, Math-2 (honors) and Math-3 (honors) classes.

Since every entry I make in this blog (about 800 by the end of the year) will show up in the center of the screen, with older entries pushed downward and the newest entry at the top, THE BEST WAY TO FIND SOMETHING is to go the CATEGORIES on the right side of the blog.  Clicking on one of the category buttons will “filter” the entries in the center of the blog to only those that pertain to that category.  You might have to scroll down a little bit within that category to find what you’re looking for.

I will cover the posted lesson plan in class.  I usually post the lesson plan and the homework for the lesson plan after it is taught.  I will do my best to get the lesson plan and homework posted by 3 PM the day it is taught.

You DO NOT NEED TO PRINT OUT HOMEWORK!  You can work off of the screen onto a separate sheet of paper.

Please see RULES AND PROCEDURES for my disclosure statement.  You can either print out the acknowledgement form or you can handwrite one out.

At the BOTTOM RIGHT side you will find some useful tools: a couple of online graphing calculators and some links to math websites.

I hope that enjoy the class!

 

 

Math-3 Lesson 8-2 Notes

March 27th, 2015

Homework is the assignment below AND to get your total time up to 1.5 hours (of time AFTER you finish the initial assessment).

In class we covered a recursively defined sequence given by
An = 2*A(n-1)-4 with A1 = 8
It looks geometric so it should have an explicit formula given by:
An = A1(r)^(n-1)
Where ‘r’ is the “common ratio” and a1 = 8. If we calculate the common ratio, it is given by:
A2/A1 which should equal A3/A2 which should equal A4/A3.
BUT none of these ratios equal each other so there is NO COMMON RATIO so this is not a geometric sequence even though it looks like one. It will be beyond our Math-3(H) ability to find an explicit formula for it. See the lesson on the blog that has been updated to show this.
