WEEK #06 . . . Cont.
CLASS #16 — WEDNESDAY, 02-14-07:   There were 09 students present today. Here's what we did.
  • ADMINISTRATIVE MATTERS   —  ASSIGNMENTS   —  QUIZES
    • I did not return the TEST PAPERS today, because I needed to REGRADE them on the correct basis of 8 points/problem, rather than on the basis of 12 points/problem, as I had actually done.
  • PRECALCULUS TOPICS
FRIDAY 02-16-07 —   Regraded TEST #01 scores are now posted on BLACKBOARD.
CLASS #17 — FRIDAY, 02-16-07:   There were 07 students present today. Here's what we did.
  • ADMINISTRATIVE MATTERS   —  ASSIGNMENTS   —  QUIZES
    • I did returned the TEST PAPERS today, and announced that I was posting my ANSWER KEY (which is also now on the PRECALC/TRIG MAINPAGE).
    • There will be an in-class quiz on MONDAY. It will be on the "Wheel of Life," which you students constructed in class today. Here's how it goes:  I give you a "wheel" with all the angle lines (these "lines" are really "rays," of course) drawn in and YOU label the 0, 30 45, 60 and 90 degree lines each with three items: (1) the degree measure; (2) the radian measure; and (3) the ordered pair coordinates of the intersection of the line with the unit circle. For example you'll label the 30 degree line with —  30 o, π /6 R, ( √(3) / 2 , 1 / 2 ). One word of caution: the 0 degree line is also the 360 degree line. See the TABLE below for complete information on this matter.

DEGREES - RADIANS - COORDINATES TABLE
degrees radians coordinates
0 0 ( 1, 0 )
30 π / 6 ( √(3) / 2, 1 / 2 )
45 π / 4 ( √(2) / 2, √(2) / 2 )
60 π / 3 ( 1 / 2, √(3) / 2 )
90 π / 2 ( 0, 1 )
360 2 π ( 1, 0 )



WEEK #07
CLASS #18 — MONDAY, 02-19-07:   There were 08 students present today. Here's what we did.
  • ADMINISTRATIVE MATTERS   —  ASSIGNMENTS   —  QUIZES
    • We didn't have a quiz today. We'll have it on WED. It will be on all the "standard" angles between (and including) 0 o and 90 o.
  • PRECALCULUS TOPICS
CLASS #19 — WEDNESDAY, 02-21-07:   There were 10 students present today. Here's what we did.
  • ADMINISTRATIVE MATTERS   —  ASSIGNMENTS   —  QUIZES
    • We had our quiz today. We'll have another on MON ( 2 / 26 ). It will be on all the "standard" angles between (and including) 0 o and 360 o.
    • I finally got the "Practice Quiz" fixed-up. You can get it from the "Quiz Box" on the 2147 MAINPAGE, or you can click here for PRACTICE QUIZ #01.
  • PRECALCULUS TOPICS
CLASS #20 — FRIDAY, 02-23-07:   There were 05 students present today. Here's what we did.
  • ADMINISTRATIVE MATTERS   —  ASSIGNMENTS   —  QUIZES
    • I returned "CIRCLE QUIZ #01."
    • We took no quiz today, but we'll have another "CIRCLE QUIZ" on MONDAY. I think that this one will be on the entire UNIT CIRCLE ==> all angles which are multiples of either π/6 or π/4. Give the degree measure, the radian measure, and the coordinates.
    • If you haven't taken the FIRST PRACTICE QUIZ, you may go ahead and take it now (i.e. before class on MONDAY.
    • Also, here is the SECOND PRACTICE QUIZ, which you may take (twice, if you wish) before class on MONDAY.
    • I don't think that we'll be taking another TEST before SPRING BREAK.
    • I am (or will be soon) putting more HOMEWORK problems on the HOMEWORK #2 PAGE.

WEEK #08  —  MAC 2147 – 48850
CLASS #21 — MONDAY, 02-26-07:   There were 10 students present today. Here's what we did.
  • ADMINISTRATIVE MATTERS   —  ASSIGNMENTS   —  QUIZES
    • We had our 2nd "CircleQuiz." And we'll have another on WED. This time you bring your compass, straightedge and protractor. I'll give you a blank sheet of paper, and you'll draw a unit circle (w/ x and y axes properly labeled), draw the 30 o line and all multiples of it, draw the 45 o line and all multiples of it, and then label each angle with its degree and radian measure AND label the coordinates.

    • We continued UNIT #02 — CHAPTER 7. We finished §7.3, skipped §7.4, and started §7.5.
    • On the graphing calculator  —
      • we graphed quite a few "partial sums" of the Fourier Series shown on page 538, and we saw how to add sine and cosine functions in general.
      • we graphed the tangent and the cotangent functions, and we observed that the period of each one was π, with the fundamental period  of the tangent function being the open interval  from - π/2 to π/2 and the findamental period  of the cotangent function being the open interval  from 0 to π.
    • Our work today was done on the graphing calculator and on the whiteboard, so there are no scanned notes for CLASS #31, WEDNESDAY (3/28).
ANNOUNCEMENT  —  MAC 2147 – 48850
