Extra Credit -- math HW for over the break!

To get the extra credit for this extra homework assignment, you must show all the work that you need to for each problem, and get at least 50% of the problems in each section correct. The link to the assignment can be found below:

HW for Dec. 16 (Thurs)

There was no homework posted yesterday (15th), as we used this day as a make-up day for missing or incomplete assignments. For the 16:

HW for Dec. 14 (Tues)

1) Graph the quadratic function y = -4x^2 + 4x - 8 on an x-y coordinate, plane by hand. Label each point that you use to draw the curve. DO NOT simply sketch the graph you see after plugging the equation into a calculator.

[hint: first build an x-y table, using x = -3,-2,-1,0,1,2,3,]

2) Use the graph of the equation above to estimate where the function's x-intercepts are. (recall that this is where the function crosses the x axis)

3) Explain in your own words why the graph of a quadratic function containing an "x^2" term (like the one above) can never be a straight line.

HW for Dec. 13 (Mon)

In case you haven't noticed...

Those of you actually trying out the HW for our class may have noticed that I have not posted any new problems for this week (Dec. 6-10). The idea was to give the large number of students who have fallen behind an 'amnesty week'; a week that they can focus on making up any of the first 4 weeks of online problems.

There will be one more week of homework before the break, for the week of Dec. 13-17 -- so be sure to check back starting next Monday. Also, I will probably post some review problems as an extra credit HW assignment, for students that can put in the effort and do some extra practice over break.

HW for Nov. 29 (Mon)

HW for Nov. 23 (Tues)

HW for Nov. 22 (Mon)

HW for Nov. 17 (Wed)

1) If you turn ______ degrees, you will end up facing the same way.

2) How many angles exist that are coterminal to 50 degrees?

3) A 90 degree angle intersects the unit circle at what (x,y) coordinate?

4) A 240 degree angle lies in the III quadrant. What would the sign of the coordinates be, at the place where this angle intersects the unit circle?

(-,-)

HW for Nov. 16 (Tues)

HW for Nov. 15 (Mon)

HW for Nov. 10 (Wed)

1) What is the reference angle for a 120 degree angle?

2) What is the reference angle for a 285 degree angle?

3) What is the reference angle for a 40 degree angle?

4) What is the reference angle for a -45 degree angle? (HINT: think negative=moving clockwise, NOT counterclockwise, from the positive x-axis)

5) What geometric shape does the reference angle help us to make?

HW for Nov. 9 (Tues)

1) If we travel 60 degrees into the third (III) quadrant, what angle would we be at? (answer with " _____ degrees")

2) If we travelled 45 degrees into quadrant II...

3) If we travelled 30 degrees into quadrant IV...

HW for Nov. 8 (Mon)

1) Which trig functions take an angle as an input, and give you a ratio of side lengths as an output? (there are three)

2) and 3) Finish through problem #6 of the 'sighted angle' word problems that we were working on in class. Show your work.

Homework for Nov. 3 (Wednesday)

We took a pop-quiz today, so no new math for the HW... instead:

1) When is the last day to make up any missing ("mi") assignments, before Q1 grades go in?

2) When is the last day to retake the pop-quiz that we took today?

3) What is so special about getting at least a 'check' on your e-homework for this first week (Nov. 1-5)?
