Sophie and Haley's D.E.V. Project

These are our videos: 














Reflections:


The reason why we chose the concepts we did was because we understood them the most. We did a graphing problem, a wheel problem, two verifying problems, and a problem where you had to find the exact values of three different values. Haley and I understood these types of problems the best, and whenever your trying to teach someone something, its best to understand the material to your fullest ability. These problems provide an overview of our best mathematical understanding thus far, because we chose a variety of problems from different units. Our first problem, which was a graphing problem, was from unit two, the graphing unit. Our second problem was a wheel problem from unit two. Our third and fifth problems were verifying problems from unit three, the identities unit. Lastly our fourth problem was from the first unit of measurement, and we did a problem where you had to find the exact values of three problems. Overall this project was a good review of what we’ve learned thus far. Therefore, I was reviewing and relearning problems and concepts that I’ve learned so far in the class. For this reason I feel like this project was educationally valuable, and made us dig deeper and expand on concepts that we’ve learned thus far in the class. -Sophie 




The reason why we chose to create our problems was because we wanted them to be on the more challenging side. We wanted something that was not too easy but challenging so that we would understand how to solve them. These problems cover all of the units that we learned. So, they provide an overview of the best mathematical understanding of what we learned this trimester in class. We wanted to make our project diverse, so we managed to cover some of the main material in each unit. This shows that we learned a lot over the units. I learned a lot from this assignment. I did not know how difficult it would be to actually come up with problems on our own. I thought that it would be really easy, however, it was actually quite a challenge. It was difficult coming up with hard problems because you actually have to solve for them. This project helped me understand how the units are all related. It also really helps you study for the exam because you are looking over all your materials. Overall, this project was very helpful and enjoyable. -Haley

The identities unit was a struggle just like all of the others. It was probably the easiest of the three units though. My fuzziest point in this unit was solving equations with tangent in it. First you had to know that tan=sin/cos. and then you had to get common dinominators and then flip and multiply. This whole process really confused me and I would always mess up one step in the process and that would give me a wrong answer. Although this was my fuzziest point in the unit I feel like I finally got it down by the time the test came around and I feel like I did well on the test.

During the couple of weeks that we worked on the past unit I found this unit was easier than the last two units.  I did not seem to have much problems doing the work and if I did I went in and got help from Mr. Jackson or help from my dad.  This unit was shorter than the other units in precalc trig.  Although I may not have gotten some questions right I still believe that I did exceptional in class.  My muddiest point was when I got confused how to complete and break down some of the problems. When I finally understood that you could use the equations to help you I started understanding more and making sure I got the problems right by checking with Mr. Jacksons problems.  Whenever I double check problema I make sure that I didn't mess up anywhere and get the whole problem right or else I won't understand how I did it for later references.  P.s. I'm sorry this blog is late. Thank you for letting me post still.

This unit was pretty easy for me. the only problem I really had with it was knowing when to use the double angle/half angle identities and I also kept thinking that sin(x +cos(x equaled 1 when it was only sin^2(x +cos^2(x that equaled 1.

Your plan has just been foiled

Identities (bob#4?)

Ok, my muddiest point this unit would honestly have to be the mud I put myself into. I have a range of challenging or pushing courses this trimester and the workload has been difficult with my schedule. Not prioritizing correctly or studying for this class as much as I probably should has affected me. I'm a straight A student with a B in this class, hmm. ;) If I could dispense any wisdom; stay on top of things and don't let yourself think you know the material if you sort-of don't. The identities unit took some stuff out of me, but I'm made up my loses and I'm hoping to pull through :)

The muddiest point for me this unit was the converting of the different sin and cos and tan unit conversions. Especially the usin of all the different formulas really made me struggle. However i was able to push past those formulas and towards the end of the unit, I had a full grasp of the information provided in the unit.
