Laws of Sine and Cosine

Objective: Students will be able to apply the laws of sine and cosine

 Example: Solve the triangle: a=2 , b=3, C=60
use the law of cosine since we are given the congruency SAS
I cannot provide the law of cosine since I cannot show squared symbol
Angle B = 79.1
Angle A =40.9
Side c = Square Root of 7

Analysis

I did not have any misconceptions with this new concept

Essential Question: How do I use the laws of sine and cosine to determine the missing parts of non-right triangles?

You can use the law of Cosine if the triangle congruenct is SAS or SSS
You can use the law of Sine with every other Triangle congruency as long as there is atleast one side. 
Take the given sides or angles and plug them into the law formulas.

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.
