Reflection |
In this quarter we learned a lot about trigonometry. Firstly, we learned the basic of sine, cos, and tangent. Then the teacher teaches us how to convert the angle from degree to radian and radian to degree. We also learned about how to draw graph of trigonometry function and how to solve the trigonometry equations. After we learned the basic skill of trigonometry we did some investigation for criteria B, C, and D about modelling using sine function, which is y= asineb(x-c)+d. After finishing the first investigation with another investigation for criteria B and C. For the second investigation we have to find at least 4 formulas, which is double angle formula. After finishing the second investigation we continued to our topic, we learned more about double angle formula. The teacher gave us an exercise about double angle formula and we should simplify the problem.
As you can see beside, that is my best work for this quarter. Why I choose that result as a evidence is because I very satisfied with the score, I could achieve 7 for criteria B and 5 for criteria C. Actually, I have prepared many thing before this investigation such as, I tried to find another way to solve some problem. Otherwise I need to improve my criteria c, which is communicating. I have to explain the answer detail to achieve good score for criteria C. I hope my score will get better in up coming quarter. |
Key Concept: Pattern and Justification
In this quarter the key concept that applied in this quarter is pattern and justification. In this quarter our topic is about trigonometric, there is a lot of pattern in trigonometric to solve a problem. Through the investigation we should find the pattern of the formula and make justification that the pattern is correct.
