PREP FOR TEST!

Hey y'all! Here are some problems (extra examples) for you to try out tonight. If you have any questions, send me a REMIND! also feel free to send a REMIND! to ask me for the answers.

Tuesday HW!

Since we didn't get through the whole sheet in class today that will be your homework. Finish as much as you can, but I need to see at least some work done for 1-4 (AT THE BARE MINIMUM).

Tomorrow, you will get a Key and you will grade yourself and correct mistakes on your own paper. I will label on the Key what I'm doing (procedure-wise) so you can all follow it.

The test will not be moved back any further! We will start review for the final on Friday so Thursday is the last possible day we can have this test.

Here is the worksheet from class:

Weekend HW!

Hey y'all!

Homework over the weekend is a couple of problems off of the grudgeball slides. They will be posted below, if you have any questions along the long weekend feel free to Remind! me (it will say that the message didn't send because its "outside office hours" but don't worry I'm still getting the messages.)

Thursday HW!

If you're not doing your homework every night (even though I haven't been checking it) then you are preparing yourself to fail this test. Tonight's homework is:

pg 364
#

• 14-16 all
• 22,23,24, 28

Let me know if you have any questions over remind!

The test is going to be next week (most likely wednesday), tomorrow we will be playing more grudgeball for review.

REMEMBER!! We are always solving for the unknown variable in an equation. In these trig equations that unknown variable is an angle every time. (so that will be your answer)

If you're interested in more examples/problems to prepare, send me a Remind! and ill send over some more examples.

Wednesday HW!

Homework is from the book tonight, and one additional problem.

Pg. 364

• # 15, 16
• # 29, 30
• sec(2x) + tan(2x) = 1

When solving tan and cot problems convert to simpler trig functions (tan = sin/cos) and determine if the numerator or denominator (of the side length) is larger, this will tell you whether sin or cos (whats in your numerator/denominator) is larger. If sin is larger then you have pi/3 (the larger angle), if sin is smaller then you have pi/6 (the smaller angle).

Tuesday HW!

Hope you all enjoyed the no homework last night. Here's tonight's HW, it's out of the book.

We will work on that worksheet tomorrow, no need to focus on that tonight.

We will start class with any HW questions and ill have the solutions to the even answers on the back board.


pg. 364

• # 11 - 13 all (using square roots)
• #22, 24, 28, 29

IGNORE DIRECTIONS JUST SOLVE TRIG EQUATIONS!

Monday HW!

Tonight there is no homework, if you have already finished the worksheet I handed out during class I will gladly give a couple extra credit points. We will finish that worksheet and more examples tomorrow.

I think you will all be relieved to hear I am moving the TEST back to Friday. We're just going to do more review this week, and GRUDGEBALL! on thursday.

Weekend HW!

The homework over the weekend is to finish that worksheet and solve the 2 problems below.

1. sin(2x) =cos(x)sin(2x)
2. csc(x/3) = csc(x)csc(x/3)

If you were not here or need an extra copy it is below:

Thursday HW

Homework is out of the book tonight.

Pg. 364
#...

• 39, 40, 41, 43, 45 (multiple angles trig)
• 81, 85, 87 (Review)

For tonight's homework:

1. Start by setting whatever is inside the parenthesis equal to theta. (Ex: tan(3x), set θ = 3x so you now have tan(θ))
2. Get the trig equation by itself equal to one thing on the other side (finshed product: tan(θ) = 1)
3. Determine what angle (θ) makes this statement true.
4. Go back to that equation in red and substitute the angle you get for θ.
5. Solve for the unknown variable (x or t or A, etc....)

Wednesday HW!

Tonight's homework is out of the book, theres one problem that is verifying if a given angle is a solution, just solve and plug in. The rest solve as you normally would, finding the corresponding angles that make the equation true. If you need any help feel free to send a Remind! message.

Pg. 364
# 3, 11, 21, 24, 27, 34, 35

Tuesday HW!

The homework tonight is just to finish up that worksheet I handed out during class. (SKIP #2, WE HAVEN'T COVERED THAT YET! If you lost it or were not in class I'll post a picture below. Try and struggle through these and come in with any questions you have.

We might have a little quiz on Friday, depending on how much we get through tomorrow and thursday. It would be on solving these trig equations, using factoring, identities, or algebraic manipulation.

We will definitely have a test on this next Tuesday so start studying over this weekend. Brush up on:

• trig identites
• the unit circle
• trig inverses

Here is the homework though:

Monday HW!

Hey y'all for homework tonight just finish up that worksheet I gave you today during class. I will post a key below, you shouldn't just fill out any missing answers off the key you should try them and then check your answers. This key is for the answers mostly, I put my process in solving them on the paper but that may not come through so clear so be ready tomorrow with questions about this homework. This is very important for moving forward because there's 17 different paths we can go down but it all depends on what you all need the most help with.

Here's the Key:

Last Blog Post!

I hope you're feeling confident about today's test!

This will be your last blog post for a while! I'll update periodically with some baby pics, some updates about when I'm popping in, and maybe some other info, but the blog will not be updated with homework each day anymore--Mr. Mason may start to use Remind for that!

No homework this weekend! But next week we start trig equations which will involve the identities and the unit circle -- so be sure you know your unit circle for Monday! Study this weekend so you can prepare yourself to start strong!

And finally, thank you all for an amazing year. I am so proud of the progress you have all made in PreCalculus! It's been an honor and a privilege to be your teacher! I enjoyed coming to work each day and working with all of you--thank you for that! You are an amazing group of individuals and I have the utmost confidence you will succeed moving forward! Even though I was very tough on you, and sometimes even a jerk, I hope you know that I was only trying to push you to give your best. I believe in each and every one of you as individuals! I appreciate all of the hard work you put in throughout the year! I will definitely miss you guys! Feel free to reach out and email me if you ever need anything--you know where to find me!

End the fourth quarter strong! Work hard with Mr. Mason to get an A and go out on top! I wish you the best of luck for the rest of the quarter and beyond!

TEST TOMORROW!!!!

Tonight...study! There are two things you can do to study: 

1. Be sure you know how to derive the Pythagorean identities! Look over your notes and our quiz from last week!
2. Practice! Look over your homework examples and today's classwork examples/key!
• Here are some problems you can try in your book for more practice:
• Page 345-346: 23, 25, 27, 29, 31, 33, 37, 45, 47, 51, 53, 57
• Page 353-354: 1, 3, 5,7, 9, 19, 41, 45, 47
• Some of these practice problems might be the same as the ones on our test! 

Here's a breakdown of tomorrow's test:

1. First you will have to derive the Pythagorean identities in at least 6 forms, referencing all 6 trig functions (same as our quiz)
2. Then you will have 11 identities to verify
3. Then there are 3 true/false questions (like today's classwork)

Let's go out on top with an A on identities! Tomorrow's also my last day, so let's send me out on a high note! Please :)

If you were out today here's the classwork so you can also use this to practice:

And here's the key to the classwork above:

Wednesday HW! (Practice for Friday's Test)

Tonight please complete the 7 "Verify Trig Identities" problems provided in class after STAR (or below)! 

• Do your homework! This is practice for our TEST FRIDAY!
• You will have some classwork practice tomorrow before our test Friday!
• Do these on separate paper! Remember the focus/grading is based on how you show your work, so don't sloppily squeeze this on the half sheet--that type of work wouldn't get you an A on Friday!

Tomorrow in class I'll provide a key and then we'll do some practice before Friday's test! See you there! Have a great afternoon!

Tuesday = Finish any outstanding homework!

Remember we have the STAR TEST TOMORROW! Head straight to the LIBRARY LIT LAB! Be on time!

• Proficient on STAR = 100% on a quiz
• Proficient on STAR = seniors need an 80 or above to be exempt
• You also must be proficient on STAR to be proficient for your SLE rating on your report card!

Seniors (HW): 

• Seniors must complete the "Trig Identities Puzzle" (Friday's sub work) for tomorrow!
• This will be collected and graded as a quiz
• Be sure to neatly and clearly show all of our work--remember, I'm grading your process (your work), not your final answer!
• Feel free to do this work on separate paper! Just # every problem and be neat/organized/clear!

Otherwise if you have any outstanding homework with identities you can show it to me tomorrow for full credit! No makeup homework will be accepted after tomorrow! However, I'm not going to tell you if you're missing something--you have to check the gradebook and use the blog to find any assignments!

After STAR tomorrow we'll do some identities classwork on Thursday, then it's test time Friday! Be ready!

Monday HW!

Tonight please complete the "Verifying Trigonometric Identities Quiz" worksheet provided in class (or below)! (This is going to be checked/scored as homework, not as a quiz)

• Remember, verifying identities is all about SHOWING YOUR PROCESS
• You MUST SHOW EVERY STEP
• Work must be organized and clear so that I can follow your reasoning
• If it's not...no credit!
• "The answer" is given to us! This is all about neatly and clearly showing how we can make one expression match another
• Pay attention to exponents
• Pay attention to the variables!

This is a big week for us! Here's a breakdown of the week:

• Tuesday = more verifying identities practice/notes
• Wednesday = STAR Testing (in library Lit Lab)
• Proficient on STAR = 100% on a quiz grade!
• Proficient also means seniors need an A OR B to be exempt from the final!
• Thursday = identities classwork/practice
• Friday = Verifying Identities Mini-Test!
• (It's only "mini" because it's based on one chapter)
• First, you will have to derive the Pythagorean identities into at least 5 forms--the same as our quiz
• Then you will have a variety of identities to verify based on our practice throughout the week!

Thursday HW!

Seniors--be responsible tomorrow! If/when you miss class for "signing day" come get the classwork from the sub and do it over the weekend! Otherwise I'll have to give it to you to do as homework on Monday night!

Tonight, please simplify each of the identities below for homework--this will be check on Monday (when I'm back) along with your unit circle homework!

• Skip questions 2 and 3--we did this as our stamp today!
• Here are the questions: do 1, 4, 5, 6, 7:
• 
  

• And here are the answers so you can check:
• 1.) cot^2(x)
• 4.) 1
• 5.) sin(x)
• 6.) 1
• 7.) 1

Tomorrow I will be out! Your sub work will be collected and graded, so be on top of your game! After you finish some identity practice you will have a unit circle to complete--we can't forget about that!

Weekend Homework:

• Complete the unit circle provided by the sub
• Fill in all angle measures in radians and degrees
• Label all coordinates
• Do this without copying the answers from your book or an old unit circle--that's not going to help you LEARN this and PRACTICE! 

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

And remember, on Monday I'm checking the unit circle and the 5 identities above (in blue)!

Wednesday HW!

Tonight's homework:

• Please complete questions 9-14 on the "Worksheet--The Basic 8 Trig Identities" provided in class (or below).
• #14 is pretty tough! Here's some help...
• To start, let's just deal with the fraction--we'll worry about the "+1" at the end...
• First, use a Pythagorean Identity to substitute for the numerator of the fraction...
• Next, factor this numerator--we have a difference of two perfect squares! (If you don't remember how to factor a difference of squares, look it up!)
• After we factor this numerator we can now "cancel out" one of the "terms in parentheses"
• Now we should be left with (secx -1) + 1...
• Combine like terms and we get secx!
• And here are the answers so you can check yours:
• 9.) 1
• 10.) sin^2(x)
• 11.) sin^2(x)
• 12.) sin^2(x)
• 13.) cot(x)
• 14.) sec(x)

Tonight's Homework:

Tomorrow (Thursday) in class we'll keep working with identities--with a quiz?!

Then on Friday I will be out--you'll have some more identities to complete (sub work) that will be collected and graded; then, it's back to the unit circle--after you finish your identities you'll be given a blank unit circle to fill out!

HW and Quiz Tomorrow!

Tomorrow we will start class with a quiz--you will have to derive the Pythagorean Identities!

• Quiz = write the Pythagorean Identity in at least 5 different forms
• Your 5 forms must reference all 6 trig functions!

Tonight's homework:

• Please complete questions 1-8 on the "Worksheet--The Basic 8 Trig Identities" provided in class (or below).
• Want a head start on tomorrow's homework?
• Tomorrow's homework is to complete numbers 9 - 14! (14 involves some kind of factoring...)

Tonight's Homework:

Tomorrow (Wednesday's) Homework:

Monday HW!

Tonight please complete the following in your textbook:

Page 345: 

• 15-18 (for these matching questions ignore options c and e; you will use a,b,d,f)
• 27, 29, 31, 51, 61
• Be sure to check your answers in the book!

Some other reminders...

• We will start class with a quiz on Wednesday! You will have to write the "original" Pythagorean identity then derive it into different forms!
• Your various forms will have to reference all 6 ratios...look at our class notes!
• We will have another quiz on Thursday--12 matching questions with trig identities!
• And finally, I will be out Friday--but your classwork with the sub will also be graded as a quiz, so come focused!

See you all tomorrow for some more (and more challenging) identities!
