TEST TOMORROW!

Tomorrow's the big test! Study, study, study!

Here's a breakdown:

Multiple Choice(25 points)

• Take a look at your pre-test (image below)! Tomorrow's multiple choice will be like these, but with different numbers! (feel free to stop by before 7:30  if you want to know if you're right)

Open Ended (40 points)

• Graphing sine and cosine with changes to amplitude, period, and vertical shifts (use your 2 prior quizzes to study!)
• Writing equations given a graph or description of a graph
• Understand the graphs of tan(x), cot(x), sec(x), csc(x) (study the tables we created! Make sure you know the shapes, asymptotes, intercepts, domain, range, etc.--everything on the table)
• Inverse problems and compositions of inverses (look at your homework from the past two nights)

Homework!

Today we wrapped up the end of our unit...tonight's homework is your last bit of practice. Tomorrow we'll start some "new stuff," and then we'll have our test on Thursday. Mr. Cawley and I will both be here after school tomorrow to study!

Here's tonight's homework. Thanks to the fire drill, each class has different homework.

Period A: Complete the 8 "compositions of inverses" on the worksheet provided (image is below if you lost your worksheet).

Period D: Complete questions 21 - 29 on the back of last night's homework. (If you don't have this worksheet, scroll down to see yesterday's post to see an image of it).

Enjoy! See you all tomorrow!

Monday HW!

Back to the grind!

1. Quiz Tomorrow!
Tomorrow you have a quick (10 minute) quiz where you will have to graph each parent function (sine, cosine, tangent), and then use this to graph the inverses--arcsinx, arccosx, and arctanx. Also, you will have to identify the domain and range for each function.

2. Tonight's homework:
Tonight, please complete the worksheet provided in class. (Great work during class today, by the way!). You need to finish 1-20 and 33-41.

If you lost the worksheet you can find it below.

For those of you in Period A who walked out class before I had a chance to say, this is your homework due Monday. We only went over one example in class so it's okay if you don't understand, just be sure to have specific questions to ask. If you show up with a blank paper, and say "I don't get it" you wont get credit. If you have a little bit of work and then a question, you can still get a 2.

Things to keep in mind when doing these problems

• If you're stuck, use the unit circle.
• The sentence I put in red and made you all copy twice can be helpful.
• Make sure you check the domain and range for each function. 

Have a great weekend, and be safe after prom (I know you Juniors are crazy)!!!!

Thursday HW

So how about those inverse trig functions? Tomorrow we'll look at arctan(x) and continue to discuss the inverse functions; then, we'll start moving into some of the "problems" we have to know how to do.

On Tuesday we will finish this chapter, and that will be the end of the unit. WE WILL HAVE A UNIT TEST NEXT THURSDAY.

Tonight, please complete the following in your textbook:
Page 316: 1-7,. 28, 29

Enjoy!

TAKE HOME QUIZ TONIGHT!

Hopefully you all aced today's table to summarize the graphs of the 6 trig functions!

Tonight, you have a TAKE HOME QUIZ. Make sure you do it! If you lost the paper, you can find the questions below.

**For the take home quiz, many questions ask, "How do you know?" You want to think--"Why?" For example, #6 asks which graph has the same asymptotes as tangent. **

• You cannot simply say, "secant, because the asymptotes are pi/2 + 2(pi)(n). That is not a sufficient response.
• An acceptable response would explain WHY these asymptotes are the same. How do we find asymptotes? (Set the denominator = 0).
• These functions, tangent and secant, have the same asymptotes because they both have a denominator of cosine!

Good luck! Use your notes to help you!

The homework tonight is two Venn Diagrams: one to compare secant and cosecant, the other to compare tangent and cotangent. You should use words like "asymptote, period, even/odd, and x-intercepts" to make these comparisons, as well as comment on the shapes of the graph.

Tomorrow we will make a table summarizing the parent trig functions, and this homework will make this assignment a lot easier. Also, we've only had one homework grade this marking period so this homework can really boost your grade.

Since we rushed through the second graph in both groups, I posted both graphs. 



Have a good day!
