Weekly Reflection 9/21

Evaluation and Conversion

Objective: I will be able to properly evaluate trig functions and convert between radians and degrees.

Example: Find the degree measure equivalent of 3pi/4 radians

To convert degrees to radians, you want to multiply the (3pi/4) by (180/pi) because 180 degrees equals 1 radian. the pi underneath 180 would cancel out the original pi, leaving you with (540/4). 540/4 leaves you with 135, which is your final answer "135 degrees".

Analysis

My misconception in the beginning was that pi was used as literal pi (3.14) instead of as a unit symbol for radians. 

I overcame this misconception by asking questions and further investigating the lesson to realize otherwise. 

Essential Question 1: What is your mnemonic device to remember trig ratios


Answer: I use SOHCAHTOA because it helps me the most and was the easiest to grasp.

Essential Question 2: Explain how you convert from radians to degrees. Explain how you convert from degrees to radians.

Answer: You take whatever degrees you have and multiply it by (pi/180) in order to convert to radians. To convert to degrees, you take the amount of radians you have, and multiply by (180/pi)

Angles and Their Measure Objective: Students will be able to find co terminal and reference angles. Students will also be able to find the arc length and area of a sector. Example: Find a co terminal and the reference angle of 400 degrees. In order to find a co terminal angle, you must simply add or subtract 360 degrees from the original degree number. In this case it could be: 40°, 760°, -320°... and so on.  To find the reference angle, you must subtract from 180, 360 or the opposite depending on the quadrant in order to get the angle between 0 degrees and 90 degrees. However, you must first find a co terminal angle that's between 0 and 360 degrees in order for it to be in a quadrant. in this case subtracting 360 from 400 gives me 40 degrees, and I already have my reference angle.  Analysis My misconception was that the reference angle was always a co terminal angle I overcame this misconception by doing my own research and studying at...

Arithmetic and Geometric Sequence and Series Objective: I will be able to evaluate arithmetic and geometric sequences and series. Analysis My misconception was that a common difference was for geometric and arithmetic. While using the formulas I realized that ratio was for geometric. Essential Question:  How do I find a given term in an arithmetic or geometric sequence?  How do I find the sum of an arithmetic or geometric series?   By using the formulas provided on your formula sheet.

Recursive, Explicit and Sigma Notation  Objective: I will be able to understand recursive and explicit forms. Students will also be able to use sigma notation for series. In example one, the sequence diverges because the ratio is greater than one. You can determine the ratio by putting the the 2nd over the 1st. Analysis My misconception was that if the the ratio is greater than one it conerges, but its really the oppostie.  Essential Question: How do you determine whether a sequence diverges or converges? You can determine by looking at the ratio. If the ratio is greater than one it diverges, and if the ratio is less than one it converges.
