Over the weekend!

No formal homework over this weekend. Just make sure you know the Pythagorean identities and the different ways to manipulate it to use all 6 trigonometric functions.

I will miss you all for the next two weeks, I hope you all do very well with Mr. Carofano. No need to get all teary eyed, I'll see you all in two weeks.

Good luck learning these trig identities, and GET PUMPED FOR MY RETURN!!!!!!!!!!

Tuesday HW!

Tonight's homework was handed out at the very end of class. It is a Kuta worksheet with a ton of different identities. SHOW ALL WORK when answering each question. Anyone who was not here or lost it I will post a picture below. Look back into your notes to check identities and mess around with the question, you've gotta try things to see if they'll work so just keep trying to switch up functions.

*Also remember to put sin(x) not just sin.
*When writing the identities dont change sin(x) to y or cos(x) to x, keep everything in terms of trig functions.

When's Day

I hope you're feeling confident about today's test! We'll see inverses and the unit circle come back in a big way in a little bit when we start solving trig equations--so keep working on that stuff!

Mr. Mason will be back tomorrow and will get those graded for you asap.

Tomorrow in class we will start some new stuff--trigonometric identities! There's no formal homework for tonight, but be sure you know the following for tomorrow in class:

Study/Check out the key I posted!

The homework tonight is just to study for the test tomorrow. I have uploaded a key of the question packet that we used for GRUDGEBALL! below. If you don't end up working on the packet at least check out the critical thinking questions in there. I answer those in full sentences with an explanation of the ideas. Checking these out will do you only good, and I don't know how people will do if they don't work on those critical thinking questions.

Topics covered on our TEST tomorrow include:

1. Evaluating trigonometric inverses (sin(theta) = 1/2)
2. Graphing trigonometric inverses (graph y = arcsin(x))
1. Critical thinking questions about inverse trig functions
3. Graphing trigonometric reciprocals (graph y = csc(x))
1. Critical Thinking questions about reciprocals

Monday HW!

Tonight's HW is to finish the front page of the worksheet I handed out today during class. If you want extra practice there are a ton of examples on the back. I'll give extra credit to anyone who finishes the entire back.

Other than that just study for the TEST on Wednesday, topics covered include:

1. Evaluating trigonometric inverses (sin(theta) = 1/2)
2. Graphing trigonometric inverses (graph y = arcsin(x))
1. Critical thinking questions about inverse trig functions
3. Graphing trigonometric reciprocals (graph y = csc(x))
1. Critical Thinking questions about reciprocals

Use your prior tests/quizzes to study, the test covers everything in 4.6 and 4.7.

Friday (Weekend) HW!

This weekend's homework is the rest of that worksheet that you received yesterday during class. We will have done a couple problems during class so any questions left uncovered will just be left as the homework.

*If you lost the worksheet it is on the post below for Thursday Night's HW.*

If you want any extra practice send me a Remind! message or an email. I'll gladly whip up some extra practice for anyone willing to take the time for it.

Over the weekend start studying for the TEST on Wednesday, topics covered are:

• Evaluating trig inverse functions
• graphing trig inverse functions
• graphing trig reciprocal functions 
• critical thinking questions about trig inverses
• critical thinking questions about trig reciprocals

Thursday HW!

Tonight please complete the following problems from the worksheet provided in class (or below):

#5, 11, 12, 21, 23, 24, 25

This inverse stuff takes practice! It's essential that you take the time to do these homework assignments so that you're prepared for our upcoming test--next Tues. or Weds.! 

And of course this is all coming back to our special triangles and the unit circle! That stuff is never going away and will be a major component of your final exam and our next chapter, so study, study, study that unit circle and those special triangles!

Tomorrow night's (the weekend) homework will be some more problems from this same sheet--between 5-12 or 17-26 (we'll be skipping the ones with the triangles shown)--so if you want some extra practice do more of these! You'll also be getting your weekend homework done!

Here's the sheet for tonight's homework:

Wednesday HW!

No official homework today, just study for the QUIZ tomorrow.

Study the restricted domains and the inverse graphs.

Remember: You don't NEED to sketch a non-inverse if you are comfortable graphing without it, but if you do then YOU MUST LABEL EACH GRAPH AS THE INVERSE OR NON-INVERSE!

Tuesday HW!

Hello everybody and welcome to this glorious Tuesday, the weather has declined a bit so all the more reason to stay inside with a snack and a pencil.

If you haven't already done so, join the new remind!

Class Name: EHHSPreCalc

Class Code: mrmasoneh

If you want to sign up for the texts instead of on the app,

text @mrmasoneh to 81010

The homework tonight is:

1. Sketch y = arctan(x)
1. What is the restricted domain for arctan(x)?
2. Why do we use the horizontal line test? What does it show us about our graph?
3. Why are there real numbers on the X axis and angle measures on the Y axis on the graphs of the inverses?
• Think about y = arctan(x), Where does X come into the equation? What about Y?

Monday HW

For homework tonight I just want more sketches of those graphs that we built during class.


HW tonight:

1. Sketch y = arcsin(x)
1. What is the restricted domain?
2. Sketch y = arccos(x)
1. What is the restricted domain?

If you are having trouble with the graphs check your notes and send over a REMIND! message.

Over the break!

Your homework over break is to finish that Take Home Test. It's got some review along with a couple of the new content that we've been learning this past week. Try your best and don't forget about it. THIS IS THE FIRST TEST GRADE OF A NEW QUARTER!!!! MAKE IT COUNT!!

Also don't forget to sign up for Mr. Mason's remind (it's part of the test grade). The info is below:

We're having computer trouble uploading the test so if you lost yours or can't find it, it's alright, no big deal, just email me and I'll send over a copy.

Tonight's Homework will be out of the book, just some practice solving for arcsin, arccos, arctan of specific values.

REMEMBER arcsin(1/2) just means "the angle whose sin is 1/2"
Pg: 316
#1,2,4,6

If you are checking your answers in the back of the book some of them are not between 0 and 2π

 (this is because of something we haven't covered yet called restricted domain, don't worry about that yet) I will make up a key with all the answers and hand it out tomorrow, if you want to check your answers yourself just find the coterminal angle.

Friday: We will start class with a unit circle quiz!

• You will have 15 minutes to completely fill out a unit circle
• Label all angle measures in radians
• Label all coordinate pairs
• You have to know this stuff!
• Section 4.7 is going to involve two new graphs, and then the rest of the section will be entirely based on your knowledge of the unit circle!
• We'll also see the unit circle again in chapter 5!
• Watch some videos, review your old notes, do whatever you have to do--BE PROACTIVE IN LEARNING YOUR UNIT CIRCLE! No excuses!

April Vacation: We will have a take home test over April break that reviews the following...

• Graphing sine and cosine with changes to amplitude, period, vertical shifts, and phase (horizontal) shifts (review)
• Graphing tangent, cotangent, secant, and cosecant
• Evaluating trig functions on the unit circle
• Working backwards with the unit circle...
• For example, "If the sin(x) = 1/2, what two angle measures could x have been?"

Monday HW

Hello everybody,

As I said in class this weekends HW will be checked tomorrow along with tonight's homework.

Tonight's HW is simply:

1. Graph two periods of y = csc(x)
2. Graph two periods of  y = sec(x)

How to:

1. *First Graph the original (non-reciprocal) function*
2. anytime that function = 0 there is a vertical asymptote, mark that with a dotted line (vertical astmptote whenever we have 1/0)
3. the function will still = 1 at the same value, when sin(x) = 1, csc(x) = 1 because                  csc(x) =  1/sin(x) = 1/1 = 1
4. Flips the curve so that it no longer touched the x axis

UPCOMING TEST/QUIZZES:

1. Mini-POP QUIZ (not a pop if you checked the blog) that is graphing the 4 functions we have learned in the past couple days
1. y = tan(x)
2. y = cot(x)
3. y = csc(x)
4. y = sec(x)
2. Quiz on Thursday
1. sketching the same graphs from the pop quiz
2. some critical thinking questions about the graphs
3. Unit Circle "Quiz" Friday, so study the unit circle
4. Take Home Test (over April Break) to help review for the upcoming section that uses the Unit Circle a lot!
