Complete the worksheet calculations. (Grades Note that the same problem would be seen as the measured angle approached zero degrees, but a student would have to be infinitely far away for that. Discussion Question: Solicit, integrate and summarize student responses. Ed. You graduated from WCHS in 2012. Then state that this river does not allow those solutions because it is too deep, the current is too swift, it is too wide, you do not have that tool, etc.) High School Math provides carefully reviewed K-12 education resources, such as lesson plans, project, and problem solving activities, by topic, including Algebra, Geometry, Calculus, Trigonometry, Probability and Statistics, Graphing, and more. 9 - ), Could this method be used in the wilderness if you did not have a calculator or Trig Tables? Author(s): Michael Corral While the students do this, the teacher can measure the actual distance between the two markers; do not reveal the distance yet. Enrollment Option program which allows high school students to take college courses for free while still in high school.) So this book is not just about mathematical content but is also about the process of learning and doing mathematics. What difficulties, if any, did you encounter while completing this project? Describe any aspect(s) of the project that were unclear to you and/or could be improved. The three common trigonometry functions are tangent, sine and cosine. For example, a wide sidewalk, two lines on a football field, or a strip of grass with straight edges. Figure 1.
