Exit Slip- Connecting the Volume and the surface area formulas

1) Why is it necessary for us to combine two formulas ?
It is necessary for us to combine two formulas because it helps make the work for me easier. It helps simplify the formulas and less work would need to be done.
2) Connection: What would you need to do if you were to apply the same skill to your can ?
Well I would need get H by itself in the Volume formula then after that I would need to plug it into the surface area formula then after that I would get the surface area for my volume. That's what is think needs to be done if I was to apply this technique to my can.

Exit Slip- Varying the radius and solving for heights

1) What was the important concept of today's lesson?
The important part of today's lesson was to generalize our radius. This was important because in our PBAT we are going to keep the volume the same while changing the radius. By generalizing my function it will allow me to be able to change the size of my can but not change the volume.

2) What mathematical tool did you use today ? Why was it helpful ? How did using the tool make your job easier?
The mathematical tool I used today was the in and out table, also the Volume formula v=\pi r^2h. This was helpful because this helped me organize my data for the PBAT and it helped me get a better understanding of what I need to do on my PBAT. Using the tools made my job easier because it helped me get a better understanding of my work and get comfortable with my PBAT work.

Exit slip: My can Volume and SA Calculation

Well on Friday my classmates really didn't help me. I understand what needs to be don't in order to complete this project. I did help my classmates understand what need to be done. For example I helped Ivette understand what she had to do to get her calculations. I was able to accomplish a lot during class I finish my work sheet and got all the calculations for my can. During class the skills that I learn was how to measure a can and find the volume and the surface area. I think if i we're to use these skills out side of school was if i was trying to make a 3D shape and trying to see how much the volume would be. That how i think i'll use it outside of school. I only have one question or maybe a suggestion: Would we get a rubric of how this project would be graded? If not are you able to give us a rubric of how the project would be grade?. I personally think that would be really easy, I understand you explain what would be ask when we present but I feel it should be written down on paper because Some people do tend to forget and it would be nice just to know what are the requirements to this project and the presentation.

Writing Objectively - 2. Tables Exit Slip

These are two calculations from the two functions; this is shown in Table 1 and Figure 1. The first function is y1=4x^3 and the second function is y2=7x^3.

The first column has some values for the independent variable x. The value for x ranges from -25 to 25. This was chosen at random. The scale is set to 5, so all the important points of the graph would be shown.

These x values were plug into the function y1 and the results are shown in the second column. The y-values first decrease as x-values increase from negative numbers to zero. (0,0) is the vertex and it's also the minimum of the graph. Then, the y-values increase as x increase from 0 to positive values.


The y-values for y2=7x^3 are shown in the third column of table 1. The y-values decreases but only until x=0. Then after that x is 0 the graph increases.

Exit Slip Lesson 3 Compare& Contrast

We compare and contrast Functions by creating a chart then we lab the categories by the exponents. We start off with the highest exponent then work our way down all the way to the constant terms. This is how we compare and contrast exponent using Google docs. I think this is going to be a more easier way for us to get our math work done and handed in on time. I'm really enjoying using Google docs =].

Exit Slip For Graphing

1. One major idea that I learned today was how to use google docs to graph and create charts.
2. One Major problem I had today was writing the function in order to graph it. At first it was a little confusing but I eventually got the hang of it and now I have no problem. Next time if I have a problem in writing the function i'm just going to look back at the sample graphing we did as a class. This is really helping me prepare for the PBAT project. I'm really looking forward in starting this project. =]

My opinion On the paper.

I'm trying to stay focus in writing my math paper. I have other classes and after school activities projects I have to do as well. This is a big load of work I have to do. My ideal goal day to be finish with this is Monday and i'm going to try my best to be done by that time.

Progress Update 2

Mathematical Methods
  • How did you "generalize?"

Well I generalize my equation by first figuring out how much my width went up by. Then all I really had was to replace the number with the X value and find how much was the girth in which was h+h+w+w in which equal the girth. I actually found this very easy because the chart I had made before generalize it helped me a lot.

  • How did you set up your axes when graphing?

The way I set up my axes when I was graphing was by making a table. In this table I wrote down the maximum, the minimum and how much I should go up by. It was very easy once I had all my charts in front of me.

  • How did you organize your data into different tables?

The way I organize my data into different tables in keeping track of all the number I was going up by and working as a group with my partner. When I started to graph it became a bit more harder in keeping track of the numbers and dots, so I used different colors to help me organize my graphs and number. This really helped me a lot and when I do start my PBAT i'm going to organize it the same way.

  • What did you discover when you put all your finding together ?

When I put all my findings together I discovered that when the height is the same as the width it is going to equal the maximum volume. But as the width get bigger the volume gets smaller. I proved this by putting the height and the width the same for one equation and in the other I changed it. This is how I checked my findings. I was actually a bite surprised at my finding but happy I finish. I think this has really helped me prepare for my PBAT and i'm really looking forward to starting my project.

Questions

1. What is a mathematical paper? and what type of information should be include in the paper?
2. Do we have to write a mathematical paper?

New Project Community Box Maker

This project is about Community Box Maker. This is my first post and blog page im super excited about this and i will continue to keep you updated. =]
