Math III Midterm Review

Here are pictures of the midterm review we have worked on the past 3 days.  I hope this will help.  If you need more help with these or if it would help for me to put the answers out differently, let me know.

Here we go...

Acc. III Test # 4 Review Problems

Here's what I have for answers to the problems we had on the board today in Accelerated III.

1) ( square root of 6 - square root of 2) / 4
2) Same as # 1
3) ( square root of 3) / 2
4) - 119 / 125
5) D = 47.0; F = 55.0; e = 21.4; Area = 140.1
6) H = 52; k = 12; h = 15; Area = 89.8
7) R = 54; S = 65; T = 61; Area = 305.9
8) q = 59; Q = 77; R = 49; Area = 1580.9
9) sin(a+b) = 56/65
cos(a-b) = 63/65
sin(2a) = 24/25
cos(2b) = - 119/169
sin(2a-b) = - 204/325

If you see errors or want further explanation, tweet or email me tonight.

Math III Test Review

This morning in second block we worked on a test review for our Circles and Ellipses test.  I worked some of the problems on the Mobi.  I hope you can find them here.

I will look for some review sites and try to post them here or on the Twitter account (@MrLewisNOHS) sometime this afternoon or tonight.

Remember: what is it I find important?  What do I ask everyday?

• What are conic sections?
• What are the four conic sections we are studying?
• What is the general equation of all conic sections?
• What is the standard form of the equation of a circle?
• What is the standard form of the equation of an ellipse (both of them!)?
• What is important to remember about a and b?

Standard to General (and vice versa!)

In 2nd today we worked with taking ellipses from standard form to general form and general form to standard form.  We did a few on the Mobi and they can be found here.

If you have trouble opening it up, let me know.

Trig Equations

Here is a shot of Page 400 from the Accelerated III textbook.  These are the problems we were working on in class today.

Fun with Trig Identities

First period Thursday, 2/7/2013, I wrote a lot of the solutions to the work we did in class, out of the book and on the worksheet, up on the computer.  I have attempted to save it and make it available here.

Tell me about you...
