Trigonometry Pile-Up Project Trigonometry Pile Up! Trigonometry Pile-Up Project Reﬂection For this hallmark project, I worked on solving the “Trigonometry Pile-up Puzzle”. The idea of this project is to start with the information I have in the bottom of the triangle and work my way up through the rest of the triangles. I was asked to find the missing side lengths to calculate the length of the hypotenuse at the top of the triangle. The puzzle can be solved with trigonometry alone. The Pythagorean Theorem can also be used for some of the triangles. Final answers were required to be rounded to two decimal places. In order to get the correct answers, I made sure that my calculator was in the right “mode”. Finally, this assignment required me to display my work in an organized and neat manner. The process I went through to produce this project was to go over the context and the requirements of the assignment. I printed out the puzzle since I prefer my math work to be handwritten. I made sure to color coordinate my work with each triangle in order to not have the instructor confused. The strategies I used to solve the Trig Pile-Up project were the laws of sines and cosines. I had a pretty difficult time figuring out which law to use for what triangle but I worked it out by looking through my notes and online examples. The main resources I used while working on this project were online examples, lecture notes, and the course textbook. What I found frustrating about this project was the concept of the puzzle and how all the triangles are on top of eachother. It would’ve been easier if they were individual triangle problems. As I look at my finished project, I’m satisfied with what I’ve produced but I would like to improve my understanding of when to use the law of sines, law of cosine, or both. Despite the struggles, I managed to look over the concept of this puzzle a little closer. Solving this puzzle has helped me demonstrate the laws of sines and cosines and why we shouldn't round numbers mid-way through a calculation.
