Tuesday's HW!

Hey y'all! Our homework tonight is out of the book

pg. 264
# 7, 11, 27, 29-36 all

In order to succeed with this trig stuff we have to have a lot of practice, the more we practice the easier it's gonna get so with our Quiz on Thursday, and Test next week we want to get as much practice with finding trig values as possible. I will be here after school tomorrow if you want extra help. I am also free H period if you can't come after school.

In hopes you all will take the incentive of extra practice I've given extra credit book problems, any that you do will get you extra points. You're going to practice this anyway, might as well get extra credit for doing it today.

EXTRA CREDIT:
15,  17, 23, 25

Monday HW!

Hey everyone don't forget to finish up the KUTA worksheet that we handed out for HW at the end of class. Here's a picture of it if you lost it. ALSO IF YOU DID NOT DO THE INVESTIGATION YOU SHOULD DO IT TONIGHT, use the extra night you've been accidentally gifted for the HW!

HW over the weekend!

Over the weekend I just want you to finish up that investigation I handed out during class. I want you to think for more than 30 seconds on the last one. Think about what they're asking and then try and specify what that means but don't just look at it, be confused and stop working. You should look at it, get confused, and then try and tackle the idea/problem.

Sine, Cosine, Tangent Investigation

Overnight Thursday (Quiz and Extra Credit)

Tomorrow we will have the quiz to begin class. It will be on everything we've been doing for the past week. This will be more of a retention of knowledge quiz, so there will be no unit circle work on it.

What's on the quiz?

• finding six trig ratios (sin, cos, tan, csc, sec, cot) of a triangle, given two sides
• solving a triangle (find all unknown sides and angles)
• we have to set up a trig ratio to find an initial unknown side
• we have to set up a trig inverse to solve for an initial unknown angle
• sketching triangles from a given context
• angle of elevation/depression (which always starts it's rotation at the horizontal, just like in standard position)
• THE SPECIAL TRIANGLES AND THEIR SIDE LENGTHS!!!!! hopefully the unit circle will help you commit these to memory.

Other than quiz prep there is no homework tonight. So come in tomorrow prepped and ready to go.

Want some extra credit? 

If you complete your entire color-coded unit circle tonight--label all angle measures and find all coordinates for each point on the unit circle--you will get homework extra credit and quiz extra credit! Use the investigation instructions to get this done! Take advantage of this opportunity!

And here are the hints in case you get stuck....

Wednesday Night HW!

The homework tonight is just the SAT practice problems that I handed out in class. Here's a pdf

HW over the weekend!

Homework over the weekend is just to complete the take home test I handed out during class yesterday.

• SHOW ALL YOUR WORK! 
• Especially on the second page of multiple choice I want to see some kind of work done, whether it be an equation or just a sketch of an angle.
• NO WORK NO CREDIT!

This is your first test grade of the quarter so USE YOUR NOTES you want to boost your score as much as possible. This will be an easy test grade if you use all your resources

If you lost the test or you were out I will be putting up a pdf on the "PDF textbook and classroom assignments" link (the first link on your classroom resources on the blog.

Thursday's HW!

For HW tonight I want you all to complete that Kuta worksheet that I handed you in class.

Wednesday HW!

The homework tonight is out of the book tonight.

Pg. 274
# 9-13 (odd), 27, 47, 49, 53, 55

Tuesday's HW!

Hey Y'all!

Your homework tonight is out of the book:

pg. 274

• 1-4 (finding 6 trig ratios)
• 17, 19, 23 (for these follow instructions below)  
• draw and label the side lengths and angles of the special right triangles.(in RADIANS AND DEGREES) 
• use the side lengths of the special triangles to find the trig ratio that they ask for

REMEMBER THE TEST IS TOMORROW BECAUSE WE DID NOT HAVE IT TODAY!!

(Reference Angles will not be on the quiz, it will be used more moving forward) there are a lot of overlapping skills though, such as sketching angles.

Tonight for homework I want you to finish the entire Homework Assignment: “Reference Angles”

A tip to finding reference angles with more than one rotation is to draw it:

1.       Sketch the angle

2.       Label the reference angle

3.       Determine the measure of the angle that intersects the terminal side and the horizontal axis.

QUIZ PREP (also HW)

As I said today there will most likely be a snow day, but do not plan for it. Be ready to take the quiz tomorrow but if the snow does come just remember to brush up a bit during the snow day or before school so you can get your brain back into math.

The HW is just to finish the packet. I'll be attaching a key at the bottom so check your answers and make sure they're right.

The quiz will contain:

• Sketching angles given in radian measure
• conversion from degrees to radians
• conversion from radians to degrees
• finding complementary/supplementary angles in radian measure
• finding coterminal angles in radian measure

Some common troubles

• CONVERT FROM DEGREES TO RADIANS: I will only give numbers in degrees that are multiples of the special angles. If you can't figure it out off the top of your head check your calculator. Attempt to divide the degree measure by 30, 45, 60, or 90.
• Also feel free to cross multiply. Set up a proportion of your angle over the whole circle equal to the x/2pi
• CONVERT FROM RADIANS TO DEGREES: Use the special angles (pi/3, pi/4, pi/6) to quickly convert.
• The TABLE: The table is meant to organize your fractions, just remember that the whole circle is 2pi (or 360), half the circle is pi (or 180), use fractions of these numbers to convert to degrees or vice versa. Try and do the table a couple of more times using different methods to find each number.
• The special angles being drawn in the coordinate plane. If I am drawing pi/3 then I cut the top and bottom PI into thirds. I then shade the first line because only the first chunk is covered by the rotation of pi/3. As you can see I labeled the pieces that I cut pi into. 

                                                pi/3

                                              pi/4

                                          pi/6

Tuesday HW!

Homework for tonight is out of the book. I'm feeling nice today so I will list out the problems but from now on I will just be posting the book problems. If you don't have a book come talk to me tomorrow at the beginning of class and we'll sort it out.

18) 3π/4

19) π/12

convert between radians and degrees

53) 115 (degrees)

61) 6.5π

Monday HW!

Hey everyone, tonight's homework is just going to be on sketching some angles in radians.

1.  -5π/6
2. -5π/4
3.  5π/3
4.  4π/9
5. -π/2
6. 9π/4
7. 17π/6
8. 5π/4
9. -7π/3

If you're having trouble try and chop the circle into fractions like we did in class.

You can use the diagrams we drew in class for reference (I've included them below).

π/4                                                                                                   π/3                                                               π/6
