Extra Credit Assignment

May 14, 2018 / / 0 Comments

This assignment is inspired by Julia’s amazing distracted boyfriend/freshman’s dream meme find. Your assignment is to make your own math meme. The rules are:

  • it has to involve real math (it doesn’t have to be math from this course)
  • it has to be family friendly (nothing too racy)
  • it has to be your original content (not copied from somewhere)
  • you may submit as many different memes as you like.

You might like to use an online meme generator like the one here. Do your best to make your meme relevant and funny, like Julia’s. This might be hard; I’ll include one of my own but it won’t be very funny.

Part 1

Submit your meme as an OpenLab post by Tuesday, May 22 at 10am with the category Extra Credit. Everyone who submits at least one meme will earn one point toward their participation grade.

Part 2

After everyone’s memes have been posted, you will vote for the best one. You will vote by commenting on that OpenLab post with just the word “vote.” Votes are due by Thursday, May 24 at 10am. The person with the most votes will earn an extra 2 points, added to their overall grade (in addition to the participation point).

 

Expanding brain meme with captions (1) I like memes (2) I like memes about math (3) I'll make a meme about math (3) I'll make my students make memes about math and send them to me for extra credit

Survey & Webwork

May 10, 2018 / / 0 Comments
Survey

At the beginning of the semester, I announced that our section of MAT 1275 is an Opening Gateways section and that, for the most part, this would only be a behind-the-scenes difference. As a student in an Opening Gateways section, however, you are required to complete a short survey. You can read the consent details at the top of the form. Please answer honestly; I will not see your responses.

(I may be able to obtain the list of names from the survey administrator; if I can, completing the survey will be good for one participation point.)

Webwork

All old Webwork sets have been reopened and are now due Wednesday, May 23 (the night before your final exam). You may continue working on them to improve your grade.  Pay careful attention to the times that the sets are due:

  • There are 6 sets on exponential and logarithmic functions (those whose original deadlines had not passed). These are due at 11:58pm:
    • ExponentialFunctions
    • LogarithmicFunctions
    • LogarithmicProperties
    • CompoundInterest
    • ExponentialEquations
    • ExponentialEquations-Calc
  • All remaining sets (those whose original deadlines had passed) are due at 11:59pm as usual.

Test #3, Review

May 8, 2018 / / 0 Comments

Webwork, TrigEquations, Problem #5

Find the principal root of this equation:

Tan(x) – 1 = 0

Tan(x) – 1 = 0
+1                  +1

Tan(x) = 1

(Tan-1 )Tan(x) = 1 (Tan-1 )

x = 45°

x = π/4

The Principal Root of this equation is π/4

Test #2, Review

Distance Formula, Midpoint and Circles, Perpendicular Bisector, Chapter 9, Section 9.1 Page 751, Question #5

Use the distance formula to find the distance between the two points. (6, 7) and (3, 2)

d = √ ( ( X2 – X1 )² + ( Y2 – Y1 )² )

d= √ ( ( 3 – 6 )² + ( 2 – 7 )² )

d= √ ( ( -3 )² + ( -5 )² )

d= √ ( 9 + 25 )

d= √ ( 34 )

Test #3 Review activity

May 8, 2018 / / 0 Comments

Test #3 will be held in class this Thursday, May 10. Check the schedule for the topics covered. The test will cover sessions 18-25 (all of trigonometry).

Like for Tests #1 and #2, choose one question from Webwork, textbook homework, or the final exam review sheet to complete and share on the OpenLab. Don’t forget to add the category Test #3 Review before you publish your post. Let us know in the post title where the question is coming from. Posts are due by 10am on Tuesday, May 15 (despite being after the test; posting before the test is better).

Do your best to choose problems that you think others might struggle with.

This assignment will count toward your participation grade.

Test #3, Webwork TrigEquations, and Law of Sines link

May 3, 2018 / / 0 Comments

Test #3 will be given in class next Thursday, May 10. It will cover sessions 18-25 of the schedule (all of trigonometry).

Webwork TrigEquations has some questions about principal roots where it will accept one answer only. This differs a little from what we called principal roots in class. You can look at section 6.2 for a detailed explanation about what makes a root principal (the ranges for the angles depend on which inverse trig function you’re using). Don’t worry too much about the exact definition of principal root for now; I won’t ask you for them using this language on next week’s test. For Webwork, you can use your calculator’s inverse trigonometric function button and for the most part, it will give you the principal root that you can enter. Webwork still might not accept your calculator’s answer for #5, but there will be only one other candidate root in $[0,2 \pi)$ and Webwork will accept that one.

Here is the Law of Sines animation from today’s class. You can play with it to see that the SSA case might be ambiguous when you’re using the Law of Sines to find an angle.
