Math 521A:
- We corrected the homework and completed a calculator exercise.
- We will correct those on Wednesday. On Wednesday, as well, I will hand back the journals and review quadratic equations.
- Homework: Prepare for in-class test or complete some of the quadratic equations that were on the handout from last day.
Math 621B:
- Pascal’s Triangle was developed using combinations and the many patterns associated with the triangle were discussed.
- The patterns found within the triangle were used to help expand binomials.
- A few examples were completed and odds 1 – 9 on page 356 were assigned.
- Homework: Complete the problems that were assigned on page 356 and start reviewing your material on Trigonometry for your final.
Math 621A:
- The formula regarding arc length was given and a couple of examples were completed.
- The following questions were assigned: page 167 – 168 10 ace, 11 aceg, 14 ac. These appeared to be straight forward since there were no questions when everyone was finished.
- A chart containing angle measures from 0 – 180 degrees, and 7pi/6 – 2pi was completed for sine and cosine.
- The graphs for each will be completed tomorrow and we will discuss our results.
- Homework: Review material on combinatorics to prepare for your review and the final.
