Last Chance for Extra Credit!

Happy Halloween and Happy Homecoming! Have a blast this weekend! Have fun, hang out with friends and family, and be safe!

This weekend you have no "official" homework. However, here is your last extra credit assignment/opportunity for the quarter:

Page 333: 27, 31, 49-52, 85, 89

• Complete these on separate paper and turn them in on Monday to boost your first quarter grade!

After you do your extra credit, rest up, relax, and be ready to graph cotangent, cosecant, and secant on Monday!

Oh, and be sure to listen to these tomorrow!

Stamps Due Tomorrow!

Your only homework tonight is to get your stamps together--they're due tomorrow!

Stamps due tomorrow!

• Count up your stamps (double check!)
• Staple them together/put them in an envelope/bag, and write the total on the front!
• If the total on your paper does not match your actual total you'll get a 0! Double check!
• Stamps must be turned in by Friday!
• You're literally counting the number of blue ladybug stamps you have! 

Once you're stamps are ready (or if you've already turned them in), enjoy you Thursday without homework!

If you'd like to get a head start, the "evaluating trig ratios" review worksheet below is due Monday! And it's the first homework grade of the second quarter, so I'm definitely checking, and I'm counting it as double!

• **you MUST SHOW WORK on the homework to receive full credit! If you're homework is just a bunch of circled answers with no work, you will earn a 0!**
• Feel free to show your work on separate paper!

No HW = Count Your Stamps!

No homework tonight! Tomorrow we'll get started on our next section, graphing tangent, cotangent, secant, and cosecant...it's going to get crazy!

Since there's no homework, tonight is a good night to get your stamps together!

Remember, stamps are due this week (by Friday)!

• Count up your stamps (double check!)
• Staple them together/put them in an envelope/bag, and write the total on the front!
• If the total on your paper does not match your actual total you'll get a 0! Double check!
• Stamps must be turned in by Friday!
• You're literally counting the number of blue ladybug stamps you have! 

"Quest" Tomorrow, Extra Credit Opportunity Below!

STUDY! 

Tomorrow we will have our "quest" on graphing sine and cosine. Here's what's on it:

• There are 3 problems where you have to graph a given trig function (sine or cosine)
• Remember to look for any vertical shifts and draw a new midline
• Then, use the a value to determine the amplitude, and draw dotted lines for the max and min values
• Next, we find the period (2pi/b!), and use this to label the key points on our x axis
• Finally, sketch the function!
• The shape depends on whether this is a sine or cosine graph
• Also, pay attention to any negatives to see if the graph is reflected!
• This is the same stuff that was on your take home quiz!
• For one of the three graphs, you are asked to graph two periods (you can add a second positive period, or a negative one, you're choice)
• Next, you are given a description of a function, and asked to write the equation
• For example: "Write the equation of a cosine graph that is not reflected, has a period of 6pi, an amplitude of 3, and is shifted 4 units down."
• You have to describe two differences between the graphs of sin(x) and cos(x)
• Next, you have three problems where you are given a graph and asked to write the equation
• We discussed this and have examples from Monday!
• First, find the midline (remember, midline = (max + min)/2
• Next, use the midline to determine the amplitude
• OR, amplitude = (max - min)/2
• Third, we have to use the period to solve for b
• Remember, period = 2pi/b
• OR, remember that b represents "the number of complete cycles between 0 and 2pi," so it is possible to find b by looking at the graph!
• Finally, determine if you have a sine or cosine graph and whether or not it's reflected (-)
• Write your equation!
• Finally, you have two questions where you are given a function and asked to describe any reflections, determine the amplitude, find the period, and describe any shifts
• For example, if I gave the function y = -4sin(2x) +1
• Amplitude = 4 (look at the "a," and remember amp. is always positive)
• Reflected? yes (because of the negative)
• Shifted: "up 1" (because of the +1)
• Period = 2pi/b = 2pi/2 = pi
• Study our stamp problem from today!

If you'd like to get some extra credit on your test grade, complete the 3 problems that were written on the board (or below) on separate paper. The number of extra points you earn will depend on whether your answers are correct or incorrect. So, do these on separate paper and bring them tomorrow for some extra test points!

Good luck studying! Check out the blog post from Friday for some videos that can help with graphing! 

And lastly...Remember, stamps are due this week (by Friday)!

• Count up your stamps (double check!)
• Staple them together/put them in an envelope/bag, and write the total on the front!
• If the total on your paper does not match your actual total you'll get a 0! Double check!
• Stamps must be turned in by Friday!
• You're literally counting the number of blue ladybug stamps you have! 

Monday HW

Tonight, please complete the 4 graphs provided in class (or below)!

Tomorrow we'll wrap up this unit and get ready for our "quest" on Wednesday!

Also, remember, stamps are due this week!

• Count up your stamps (double check!)
• Staple them together/put them in an envelope/bag, and write the total on the front!
• If the total on your paper does not match your actual total you'll get a 0! Double check!
• Stamps must be turned in by Friday!
• You're literally counting the number of blue ladybug stamps you have! 

HW = Take Home Quiz!

This weekend, please complete the classwork we started today in class. Remember you can skip questions 7 and 8. This will be collected and graded on Monday as a 31 point take home quiz! 

YOU WILL LOSE 5 POINTS FOR EVERY DAY THIS IS LATE. NO PAPERS WILL BE ACCEPTED AFTER WEDNESDAY. NO EXCUSES!

We will have a quiz/test (quest?) on this same stuff on Wednesday! So, if you put in lots of effort on your take home quiz, not only will you get a better grade, but you'll be better prepared for your "quest!"

• When I'm grading the graphs, I'm looking for 5 pieces (each @ 1 point):
• Period (so show the work on the side!)
• X Axis labeled
• Correct vertical shift (midline)
• Correct amplitude (show dotted lines for max/min values)
• Correct shape (pay attention to if it's sine or cosine, and if the graph is reflected)
• For question 3...
• First solve for b: you know the period is "3pi," so 2pi/b = 3pi. Then, cross multiply to solve for b!
• Remember, it tells you this is a cosine graph!
• This is reflected--how do we show that in the equation?
• The amplitude is 7--where do we see that in the equation?
• And lastly, there is a vertical shift "9 down"--how do we see this in the equation?
• Try questions 7 and 8! You can get up to 4 extra credit points for each!
• To write these equations (we'll talk about this Monday), FIRST, find the midline
• Remember, the midline is halfway between the max and min!
• This gives us our "d"
• Then, find the period--how long does it take to complete one cycle of the graph?
• Once we determine the period, set up an equation to solve for b (like the first bullet for question 3 above)
• Next, consider the amplitude and if the graph is reflected to determine the "a" value
• Lastly, decide if this is a sine or cosine graph!
• Write your equation!
• You got this!

Here are the questions you need to do (in case you lost yours). Use axes like the ones below for each of your 5 graphs.

Feel free to email with questions! Also, check out some videos on youtube for help with graphing! I provided some helpful links below! And most importantly, USE YOUR NOTES!

Graphing Trig Functions (Period, Amplitude)

Graphing Trig Functions with Vertical Shifts!

Thursday HW

Tonight you have the shortest homework assignment ever...

Please graph the following function: 

y = 3sin4x - 4

Tomorrow we'll do some classwork/practice with graphing vertical shifts! See you there!

Enjoy your long afternoon!
