Math9

In math 9 (the basic freshman year math class)  we learned the basic algebra, trigonometry, pothgremtherium  equations and more. Although I don't see myself as good at math I didn't struggle in this class or struggle to keep my grade up. I think that in the future the base that we formed in this class will help me succeed in future math classes. We do a lot of practicing what we learn with worksheets, group collaboration and POWS. Not very often we take tests to see how well we are doing but we seem to have enough work to help us do well on the tests. 

The central problem was Edgar Allen Poe and the pendulum. We didn’t know how long until the pendulum would hit the character and if he would have time to escape the pit. Variables such as the length of the pendulum string, the weight, and the angle of the release. We measured the time it took different pendulums to complete a full swing back and forth while also noting the variables in effect. We learned about this process as well as graphing, curve fitting, map the data points on the graph, found means, mode, range, and sigma. These skills helped us come to a conclusion of if the character would be able to escape the pit in time before the pendulum kills him. We modeled the pendulum as a class and timed it. We used the math that we learned as well as the equation T = 0.33land made an equation to estimate how long it would take for the 30 foot pendulum in the story to swing 12 times. One time would take 6.26 seconds. We multiplied this and got 75.12 seconds or, a minute and 15 seconds. We came to the conclusion that this would not be enough time to escape the way the character in the story was trying to do so.

The topic from this unit that was the easiest for me to under stand would probably be Pythagorean theorem or factoring. I felt that these were easy to get down after practice and I felt that I was able to get a hang of them fastest out of all the things that we learned.  The topic that challenged me the most would be simplifying and expanding certain problems. Ive done these before in prevoius years but I think that I forgot how to do it with certin cenerios and so it was hardest for me. If I was  to explain factoring to  someone that missed class I would tell them to first  find a number that each of the numbers in the equation can be divisble by. Next I would tell them to devide each of the numbers by that number and place the sum of that back into the equation. Next they would place the  number they divided with  on the outside of parathesis.
