Final Assignments

It's finals time and you want to get the most out of the time you spend preparing for the final. We discussed several options today in class, including Youtube, Flickr, and Twitter. I have also assigned work for you to complete over the next few days. Here are the specifics:

1.) Create a question on the final

Good examples can be found on your previous tests, chapter reviews, and daily quizzes. You might even find some if you search online. Each student is responsible for contributing one solid question on googledocs. Leave your name next to your submitted question. Here are the break down for the areas you should be creating questions from.

Last Name

A-F, Chapter P.1-P.4

G-L, Chapter 1.1, 1.2, 1.4, 1.5

M-S, Chapter 3.1-3.4

T-Z, Chapters 5.1-5.3

2.) Twitter Fun

Post one, two, or more useful facts on twitter with the tags #jcadraytrig and #trigfinal.

3.) PBWorks

Post a question and/or an answer to the question bank on PBWorks

Finals

SEMESTER TWO, 2010 FINALS ARE JUST AROUND THE CORNER.. LITERALLY.

I did some great research and i found some really helpful study guides online and review sheets that you can print out and start reviewing this weekend before the final, hopefully, this weekend wont be the first time you have started on finals review..ha

1st site.

http://math.boisestate.edu/~tconklin/MATH147/Main/Extras/TrigBasic.pdf

(this site is awesome, its basically a huge flash card) great fun

2nd site.

http://www.cliffsnotes.com/study_guide/Fundamental-Identities.topicArticleId-11658,articleId-11608.html

(this site includes a basic overview of fundamental identities)

3rd site.

http://www.sparknotes.com/math/

(this site rocks, its basically a list of units and concepts we have covered this term, towards the bottom of the page, there is a section for trigonometry, also it has a good basic review of geometry, if anyone needs another review of there special triangles, since those are involved in trigonometry.)

I hope everyone has had a great last full week of school, and i hope everyone is starting to get excited for short term, its so close!

have a great day and weekend everyone

** if anyone is interested in getting a study group sometime next week, monday or tuesday, let me know, i can help organize that. Last term we did that and it helped a lot.

Hey Everyone!

So today Jojo wasn't here today because the girls had a track meet (Good Luck by the way!)

So today in class we had a chance to catch up on the homework and continue preparing for the test on Wednesday. Remember the test is on Chapters 5.1-5.3

Don't Forget to finish the homework(assignments and flickr) and study! Its our last test before the final. So work hard and don't give up we are almost done! Nest Scribe is Nigel!

Math and Philosophy

Here is an interesting link to an interview with James Franklin, a senior lecturer in mathematics at the University of New South Wales. The interview is about the connection between mathematics and philosoph, Franklin says that, "philosophy and mathematics are the two great armchair disciplines, and it is time there was a rapprochement between the two."
So yeah, pretty interesting.

Scribe Post

On Friday in class we covered general homework problems, but the main thing that we covered was when to combined like terms and when not to. For example:

x² = 10² + 14² −2(10)(14)cos(44°)

x² = 296 −280cos(44)

x² = 94.6

One can not combined 296 to 280cos(44), because they are not like terms.

SCRIBE POST

Today in class we learned new information from this unit! Jojo wrote on the board a lot and we did some very interesting problems.

Today we learned about:

1. The Ambiguous case.

2. how to do problems using certain rules for triangles based off of their sides (S) and angles (A).

I have scanned my notes and posted them below because I think they are easier to understand than a typed format of the problems we did. My notes include the rules for ambiguous case, triangles, and two practice problems that Jojo did on the board.

I hope that these notes were helpful. Today at the end of class Jojo said "I feel a daily quiz coming!", so prepare yourself! Tomorrow Jojo said he is planning on doing additional review for the test next week. Do not worry too much about final exams and have an excellent Friday and weekend.

Upcoming:

Our next test is Monday, April 26 and it covers chapters 5.1-5.3. Start getting ready for it so you don't have to worry about it during "Bash weekend"!

Our Final Exam is on May 6 and it is the first exam of that day.

The exam will cover: Trigonometry Chapter P, 1, 2.1, 3, 5.1-5.3.

Trigonometry: Oblique Triangles- The Ambiguous Case... And quotes...

As I was perusing through the search results from when I looked from the site which Jojo posted (thanks Mirranda for posting it) I happened across this site, which is also quite helpful in discussing oblique ambiguous triangles: http://www.algebralab.org/studyaids/studyaid.aspx?file=trigonometry_lawsines2.xml




An interesting quote: "We have to live our life as if we are dying of a fatal disease. Because we are." -Phineas Narco

Also, if you're feeling stressed about finals remember what Winston Churchill said: "when you're going through hell...keep going!" And Ealanor Roosevelt: "you must do the thing you think you cannot do."

And a quote that I think Jojo will like, "To live a creative life, we must lose our fear of being wrong." -Joseph Chilton Pearce

Just some quotes which I found on The National Cynical Network's website :)

More help!

Here is a visual of an ambiguous triangle. This is what we went over in class today wit JoJo - this is an example of the triangle he drew on the board, but with each case in the same image.

Remember the rules for ambiguous triangles!
- One solution -- a=h, a (greater / equal to) h
- No solution -- a (less than) h
- Two solutions -- h (is less than) a (is less than) b. In other worlds, if a is in between h and b.

Site in class today

Here's the Website we used in class today.
Enjoy!

Scribe Post, Trig (Oblique Triangles) , William Tabor

Today we talked about the "Ambiguous Case" and when to use it. There are three parts to the "Ambiguous Case."

1. When a=h or a is greater than or equal to b, you will have one solution when solving for the angle of an oblique triangle.

2. When a is less than h, you will have no solution for the angle of your oblique triangle.

3. When h is less than a is less than b, you will have two solutions for the angle of your oblique triangle.

We solved problems which involved these situations. We were able to grasp most of it and will continue with this tomorrow.

For more information on the "Ambiguous Case" I have a link to a list of videos that may help you, many of them were good so I will let you watch them and decide which one helps you the most.

http://www.youtube.com/results?search_query=ambiguous%20case&search=Search&sa=X&oi=spell&resnum=0&spell=1

I know myself and many others in our math class like music and I try to give everything a chance so listen to Sherman Downey and the Ambiguous Case's song "Keep Your Head Up."

Keeping your head up is something you all need to do during finals, you will make it, believe me.

Law of Sines and Cosines practice

This site is pretty mundane and boring when it comes to explaining how to use the law of sines and cosines BUT if you scroll down all the way to the bottom of the page they have a problem generator that gives you different triangles with different angles and side measurements. It's another good way to practice w/o the book before the test on MONDAY.

What up world.

Today Jojo was back in class :) We went over a bunch of the problems on the worksheet really throughly to make sure everyone understood all of the steps involved in solving them. We got so into it that we didn't have time for a DQ.

The Law of Sines

The Law of Cosines

Here are a few websites that I've found to be helpful in explaining the processes that are necessary in problems that require the use of the law of sines and the law of cosines. Ch-check it ouuut.

Laws of Cosines & Sines

This site doesn't include any example problems, but it gives you a pretty good idea of what's going on, but they used different variables than we're used to, which can be confusing.

Law of Cosines: Interactive Triangle

I think this one's pretty cool. You can plug in values for sides a, b, and c, and angle C and it solves the triangle based on the law of cosines.

Trig Topics - Law of Cosines

Not only does this site give us straightforward explanations of how to solve triangles using the law of cosines, but it includes a few example problems (and an answer key) as well.

April 15 & 16--Kharon--chapter 5

So these two class days our teacher, Joseph "JoJo" Cadray III, was in memphis attending a wedding. So while his wonderful trip we worked on various things. We did test aftermath for those who took the test on april 2nd, others finished the test and/or took the test as well. The next day Im sure JoJo was enjoying himself on a nice break from trig and triangles and the laws of sin and cosin, but in class we were working very hard on a work sheet about the area of trig. We all worked on the the 4 question worksheet and running into various problems on the worksheet. So while JoJo was out the class was still studious and was working hard on understanding and getting more familiar with trig! :)

the next scribe is Anna! :)

That Worksheet today...

So, alot of people had trouble with that worksheet. Let's all post our problems down below, and then maybe we can work out the problems... For instance does anyone know how to get the TWO angles for number three? In the 3rd class we worked out one way (which I will post later tonight), but I don't think anyone's really sure about it... Also for number three how can C be an acute angle if it is a right triangle and c=hyp?
For number four I don't think anyone in the room during 3rd prd. knew how to do it, what is "n?" That was one of the big problems...

Law of Cosines: More examples and explanations, similar to the last post

So this is another site I found, it might help those of you who need to see the law of cosinese explained from a different perspective... I, for one have found this law very difficult to work with in the homework that was assigned tonight...

This is pretty nifty, it also might help those of you in physics... maybe:

April 13, 2010 (improper title-see directions for scribe posting)

Today we went over some of the homework problems in class with help from JoJo. We went over 36, 37 and 40 as well. After wards, he checked our homework. Then Kharon came into class looking half dead from the copious amounts of pollen everywhere. Once he finish checking our homework he began learning 5.2. And watched a video that helped to explain the new material. it was mainly about oblique triangles & how to the angles, and side length. I've included the website Luke posted so that it's here . :)

Oblique Triangles!

Here's a nice page that I found on oblique triangles:

Ocean waves as Sinusoidal Functions

Ocean waves are represented as Sin Cos and they are transverse waves.

Wolframalpha

Hey, so this is an amazing site that my aunt gave me, you enter a problem... and it solves it. It also goes through all of the steps... Try putting in cos(a)+(1/(sin)) (just type it in, no equation editor or anything of that sort) and see what you get... It's pretty nifty...

Well here y'all go:

Tutorial

I don't think this was shared to everyone (Not sure why, sorry) but here's the tutorial for this test. I'm so sorry that it's this late. Something must've screwed up.
