1/23: go over review sheet challenge sheet
1/25: Review more? Radicals and Pythagorean Theorem
1/26: MorePythagorean
1/29: Trig Packet
2/1: Trig Word Problems (did 3 word problems for review) then went over the unit circle, sin curves, and radians
2/2: Trig Cheat Sheet Go over other trig functions (Sec, Csc, Cot). Have students keep the sheet for reference. Fun with trig graphs
2/5: Go over trig graphs as a class on Desmos
-set x-axis in terms of pi, use the unit circle to explain what is going on (start with Sin)
-cover cosine, tan, sec, csc, and cot.
-Assignment: Research what Sin or trig functions can be used for (either as a wave or as a trig function with triangles)
Trig Sheet (first 3 questions)
2/6: Hand Graphing Trig Functions:
2/8: Law of Sines Proof then Law of sines sheet
2/9: More Law of Sines
2/12: Law of Cosines Proof (also a different Law of Sines proof) then Law of Cosines
2/13 and 2/15: Law of sines and cosines together
2/16 Law of Sines and Cosines together (word problems)
2/26: The Joy of Stats
2/27:
Then do Trig Review
3/1: roll dice as a class 20 times...how many 6s do you get. Graph as a group...show the normal distribution.

3/2: Explain the difference between two-variable and one-variable data analysis. Review what a z-score is, what a mean is, and what a standard deviation is.
In groups of 1 to 3 students, choose a data set you believe would be normally distributed. Examples would be height in adult males, shoe size in females, hand width...etc. Please choose your group, your topic, and then come to me with a plan for how you will collect 20 data points. Find the mean and the standard deviation of your set of data and do your best to graph your data as a normal curve. If you need help from technology, try this: Normal Curve Calculator: https://www.desmos.com/calculator/whjdy2cmx7
I will collect the table of your data and your normal curve graph.
Research what variance and z-scores are and complete the following paper, page 10, individually:

-divide variance by n-1 instead of n: https://www.khanacademy.org/math/ap-statistics/summarizing-quantitative-data-ap/more-standard-deviation/v/review-and-intuition-why-we-divide-by-n-1-for-the-unbiased-sample-variance
