Welcome back! Quiz Tomorrow!

Welcome back! I hope you all had an awesome break of resting, relaxing, and lots of eating!

I'm looking forward to getting back to work tomorrow! Be ready to work hard as we continue to push through these trigonometric identities for about another week, with some quizzes along the way.

Tomorrow we will start class with a quiz: write/derive the Pythagorean identities in at least 5 different ways/forms! You'll have about 7 minutes to do this. Whether you memorize the identities or understand how to derive them, that's up to you--but get an A tomorrow!

If you were out today you missed the STAR test; you will have to make it up! (Classwork grade)

After our quiz we'll get into some more practice! See you there! Have a great Monday!

Happy Thanksgiving!

Enjoy your break! Rest up, relax, enjoy some time with friends and family, and be ready for lots of intense math when you return!

Over break, please be sure to complete your trig identities take home quiz (DUE MONDAY)!

• Remember, it's your work that I'm looking at when I grade these...so be neat and organized, and show all work!
• In the answer bank you will use option E (secX) twice and you will use option S (1) twice. 
• All of the other options will be used once.
• DO NOT FORGET TO GET THIS DONE--IT'S A QUIZ GRADE!

Also, remember that we have the STAR test on MONDAY (11/30) AFTER BREAK in the LIBRARY MATH CPU LAB! 

I will still be collecting your take home quizzes Monday, so don't forget!

Have an awesome break! See you in a few days!

Here's the take home quiz:

Monday HW

Tonight, please complete the following in your textbook (I'm checking!) These problems are on the printed copy I gave you in class, so you may not need your book:

Page 345: 15-18 (eliminate matching options c and e), 21-25 (eliminate matching option D)

Weekend HW

This weekend, please complete the "Introduction to Trigonometric Identities" worksheet provided in class (or below)! 

I'm definitely checking!

Have a great weekend and I'll see you all on Monday!

Thursday HW

Tonight, please complete the "Trig Identities and Algebra" worksheet provided in class!

Make sure you do it! I'm checking! AND, this is the foundation for the math we'll be doing moving forward, so start strong!

See you all tomorrow for some more identities!

Here's the homework in case you lost it or were absent!

No homework tonight!

How are you feeling about today's test? Hopefully confident! I'm looking forward to grading them and seeing lots of A's!

Tomorrow we get into some intense math with trigonometric identities; we'll start by reviewing a variety of algebraic strategies, including factoring, "foiling" or multiplying polynomials, and finding common denominators. See you there!

Have a great Wednesday!

Test Tomorrow!

Tomorrow we have our first test of the second quarter! STUDY! This will have a major impact on your class average!

Here's an outline of what's on the test!

• 10 multiple choice questions
• Study the 10 pre-test questions we discussed in class today! (Same questions with different numbers tomorrow!)

• Open Ended:
• Graph sine/cosine with vertical shifts, changes to period, amplitude, and reflections
• Write equation of a sine/cosine function given the graph
• Write equation of a sine/cosine function given a description
• Know how to find x-intercepts/asymptotes for tan(x), cot(x), sec(x), csc(x)
• Evaluating inverses (like tonight's homework)
• There are some true/false questions dealing with...
• Asymptotes
• X-Intercepts
• Domain
• Range
• Study the trig functions summary table from the weekend!
• Graph arcsin(x), arccos(x), and arctan(x)
• You will have to graph one of these three functions on the test!

Monday HW and Test Weds!

Tonight, please complete the 16 "Evaluating Inverses" problems provided in class (or below).

Tomorrow we'll wrap up our discussion/notes and do some review to get ready for Wednesday's test!

Start studying now! Here's an outline of what's on the test!

Weekend HW!

This weekend, please complete the summary table for the 6 trig functions (provided in class or below). This is a great way to start studying for Wednesday's test!

• THERE IS A MISTAKE IN THE TABLE I GAVE YOU! The asymptotes that were given for tan(x) are incorrect! (I actually wrote the asymptotes for cot(x)
• Pay attention to the functions at the top!
• I just did mine mindlessly and graphed my functions in the wrong places and had to re-do it!

Test Wednesday:

• Graphing sine and cosine with changes to amplitude, period, reflections, and vertical shifts (section 4.5)
• Know how to graph (like Thursday's sub work)
• Know how to write equations given a graph or description of a function
• Know how to calculate amplitude, period, identify shifts/reflections
• Graphing the quotient and reciprocal functions (4.6)
• Know how to graph tan(x), cot(x), sec(x), csc(x)
• Know which functions have the same asymptotes or x-intercepts and why
• Study the "critical thinking questions" we discussed in class!
• Evaluating trig inverses with a restricted domain (4.7)
• Graphing inverses
• Know how to graph arcsin(x), arccos(x), and arctan(x) and determine the domain restrictions
• Evaluate compositions of inverses (4.7)

Here's your homework in case you lost it!

Back to Inverses Tomorrow!

I'm sorry that I was not there with you today! I plan to do my best to have perfect attendance (other than my honeymoon) from here on out so we can do our best to prepare ourselves for our exams, and more importantly, so we can learn lots of trig!

Today's classwork is a great opportunity to review for our unit test, and will be graded (our first classwork grade of the quarter). Do your best!

I look forward to getting back to work and graphing arctan(x) and arccos(x) tomorrow! See you there!

Tuesday/Wednesday HW

Tonight/tomorrow, please complete the "Evaluating Inverses" worksheet provided in class.

Use the 3 examples at the top for help! If these aren't enough, take a look at the examples in section 4.7 of your textbook, or use some of the resources (links) on the right!

I'll definitely be checking this homework on Wednesday!

Here's an outline of what's coming up in PreCalc:

• Wednesday: Graph arccos(x) and arctan(x)
• Thursday: More evaluating inverses!
• Friday: Evaluating/graphing practice (classwork)
• Monday: Section 4.7 wrap up: evaluating and graphing inverses and compositions
• Tuesday: Review for test (everything from 4.5, 4.6, 4.7)
• Wednesday 11/18: TEST ON GRAPHING AND INVERSES
• Thursday/Friday: Intro to our new unit, trig identities!

Quiz Tomorrow = Homework due Thursday!

Tomorrow we will start class with a quick, 15 minute quiz! Here's what's on it:

• Graph y = tan(x)
• Graph y = cot(x)
• Graph y = sec(x)
• Graph y = csc(x)
• There will also be 2 of the "critical thinking" questions where you have to write explanations (we went over these in class...)
• For example, "Which function has the same asymptotes as tangent? Explain why." Or, "Which functions do not have x-intercepts? Explain why."

No Thursday HW!

No homework tonight! Enjoy your night off!

Tomorrow we'll complete a table summarizing the graphs and properties of the 6 trig functions (sine, cosine, tangent, cotangent, secant, cosecant).

Then, we'll get back to practicing some trig inverses! Yay!

Have a happy Thursday!

Wednesday HW

Tonight, please complete the "Reciprocal Graph Wrap Up" worksheet provided in class.

• Each answer will be sine, cosine, tangent, cotangent, secant, or cosecant, along with an explanation of WHY.
• This is our first homework grade for the second quarter, so I'm definitely checking and it counts as double!

Tomorrow in class we'll go over these (quickly), and then move on to our "new stuff," section 4.7! Woohoo!

Here are the homework questions in case you lost yours or were out:

Take Home Quiz Due Weds!

Please complete the "Evaluating Trig Ratios" worksheet that I passed out today!

• This will be collected and graded as a take home quiz on Wednesday!

• YOU MUST SHOW WORK to receive full credit
• If you simply hand in a bunch of circled answers with no work, you can at best score a 50%!

Use your notes and get an A! Start off the second quarter strong!

In case you lost your paper, here are the questions! Enjoy! See you all on Wednesday!
