Fareen, Alec, & Breanna Duck Applet

We came up with the idea of hunting a duck for our applet. First, we needed to define our bullet's path and then our duck path. For the bullet's path, we used the equations y=-(16)t^2 +v(sin)(alpha)t+s and x=v(cos(alpha))t. For the duck's path, we used the equation x=dv(cos(gama))t+d. After that, we had to learn how to change the angle of the bullet and duck. We did this by making sliders, which changes/controlled the angle of the lines. We then learned when the lines of the bullet and duck crossed within so many units of each other the duck would be shot down. Then, we came across the challenge solving aT=bT+c. Once we overcame this challenge, we started to find our variables such as distance of the duck, gun velocity, starting height of the gun, and the duck velocity. We fine tuned it, and we were finished.

We learned a lot by this project. It really helped us see the math behind just shooting a duck. We thought it would be a lot easier. Turns out, it wasn't. It really made us think, dig deep in our brains. We just had to apply things we did know to things we didn't know, and that was extremely hard, but we learned and now can really see whats the math, what's the logic, etc.
Overall, it was a fun yet hard project to do. We loved it.

Geogebra Applet

What we did was create a geogebra applet about a artillery shell hitting a castle. We created several sliders on Geogebra. One for time(t0), one for distance to the castle(d), height of the castle compared to the missile launcher(h), another one for firing velocity(v), and the final one was for the initial angle of the missile lancher(alpha). Then to get the projectile moving we input the equation h=-16*t0^2+v*cos(alpha)+s. Then to make our target we made a point across from point B. Then to show our mushroom cloud, we put the distance formula as our condition to make our mushroom cloud appear. Then to make our projectile stop, we used the rate times time equals distance. After we were all done with that, we added a few pictures to make it look better. Which made a functional geogebra applet.

Kathryn, Odi, and Ravneet's Project

For our project Ravneet, Odi and I decided to make an EVT test. At first we thought we could get this done quickly, but we found out that making a test was going to be much harder than we expected. First we had to come up with fifteen problems covering different standards in algebra. Instead of plugging in numbers though we had to represent the numbers with letters (For example ax+by=c instead of 3x+4y=12). We then had to define our variables and make our equations, wrong, and correct answers. If we did all of this correctly we could press a button to the side of our problem, the variables of my problem would then change, but the principal would still be the same (believe me this was harder than it sounds). The hardest part of making the test was finding the correct answer to our problems while in letter form. If we messed up on this then our entire problem would be wrong. The process of making and writing the problems was a little time consuming but after repeating the steps we began to get the hang of it and pick up the test. Now we have a good handle on making EVT tests. Once we got going making the test began to be a lot of fun.

Baseball Applet:Brandon M.,Marco M.,Lazaro V.

The first thing we did for our applet was to figure out some solid math so when we got to designing the applet, it would be faster and easier to create. The two equations we had for the solid math were X=(cos(a)*v)*t and y=-16t^2+sin(a)*v+s(3.5). Then we had to get values that were reasonable for baseball. Our values were 120ft/s-125ft/s for the ball speed, 310ft -450f for the fence distance, 3ft-37ft for the fence height, and 0-90 degrees for the ball trajectory. WE plugged in our two solid math equations and got two perpendicular lines thats intersection would represent our ball. Then we made our fence that the ball would have to go over. When we made the fence, we had to be sure that it would change as we changed the variables. once we had the fence, we had to make the ball stop at the x-axis. For that we had a long equation that we got from plugging in the a,b, and c values from our y equation(y=-16t^2+sin(a)*v+s(3.5)) in to the quadratic formula. We then put in images to represent our ball and batter. We then wanted the ball to stop at the fence, so we put in the equation-t=d/cos(a)*v. Finally we perfected our applet and all its values and finished our Baseball Applet.

David, Jett, and Sartaj Papa Smurf Project

Here is a project we did for math. Our project was if we could get a smurf to land on a mattress. These are the steps that we took to make this project happen.


Step 1- Define Sliders


We created our sliders for cannon angle, mattress height, mattress distance, time, smurf speed. Since our equations had to be universal instead of using numbers we used variables. An example of our time slider or our abbreviation "t0" is {t0 (-sin(angle) velocity - sqrt((sin(angle) velocity)² - 64 (height + 30))) / -32}


Step 2- Defining Point "S"


We created a point and named it s. S would be the point be defined by the falling object equation and the time equation. This made point s move with the slider in a parabolic form moving with time.



Step 3- Stopping Papa Smurf



One major thing we wanted to do was make Papa Smurf stop a our mattress height. To do this we used the falling/rising object equation and solved it using variables. Our equation looked like this 0= -16sin (a)^2+v sin (a)+h+30/32.



Step 4- Telling Papa Smurf he was on the Mattress/Text



Now that Papa Smurf was landing on a point we needed him to land on the mattress. We did this by making two points and telling the computer that if Papa Smurf was between these two points and time equaled one, a text would appear saying "Congratulations, You're Not Dead!"



With all this information we were able to make a smurf shoot out of a cannon, control the distance and the height of the mattress, control the speed of the smurf, and achieve the overall goal of landing the smurf on the mattress.

From this project we learned that it may not look like we know how to do these hard tasks, but if we really think about the skills and rules we know about math we can do a lot of cool things. We really enjoyed this project and hope other kids from other school can have this opportunity too.

The Link to my Project: http://prezi.com/tvzfj7pd6ftx/

This project was very helpful in having people understand the math behind everything. Most people like me wouldn't bother about the why in a problem but the what. That is why when doing this project it helped me realize the why in everyday problems that occur and try to answer them with the best of my ability. The farming project that I finished may not be the best, but it shows my understanding of how to takle a problem like this. Most of the problems reenforced my understanding of skills.

Fareen's Farming Project

Alex, Dil, Franky Geogebra Applet

We decided to create our Geogebra Applet about a monkey being shot out of a cannon and hitting a building. To start this we needed to know what variables we were going to use; alpha for angle, v for the velocity of the monkey, s for the starting hight of the cannon, t0 for time, d for the building height, and c for the building distance. After we had our points we desided to put on some basic pictures. One of the hardest things was to get the King Kong picture to pop up at the end. After we solved that we were able to make words pop up that say King Kong! plus we also just copied the formula and change a sign to make things disapear. After that we just spiced it up a little and done!

Abel C. Farming Project

During this project I learned many things. The first thing that i have learned is all of the skills that we have learned in class can be used in the real world. The skill that suprised me most was in task 4 by graphing ineqaulitys. I enjoyed this project alot and i thoght it was very intresting and creative. I think you did a great job on this Mr. Cox and it all flowed together very well. The only thing i really had a problem with was the unexpected due date. that is my opinon on this project.

I learned their is a reason that we do all we do. I know that there is practical uses for all the things we have learned. I know that if I ever possessed a ranch I would be better be prepared to run it. I think that the project could have been better if we had more resources giving us hints on how to do the tasks.

Real Estate Income vs. a Good/Bad Economy
Hypothesis
I believe that in a good economy that real estate agents make more money. My reason behind this is that in a good economy more people have more money and wealth which means they are willing to spend more on a big house. Meaning the value of the houses will go up causing the real estate agents to make more money. Real estate agents make a certain percent of the total costs of the house they sell. If they sell a house for cheap they are not going to make much money. For example if a house is $100 and the real estate agent makes ten percent of the total amount for the house, they will only make $10.
Conclusion
My uncle that lives in Madera makes over $100,000 a year on average. During a good year he says he can make up to $250,000 selling houses. He owns a real estate company in Madera him and his wife are both very wealthy people. His wife just recently joined him in his company and they make on average $350,000 a year. My uncle Frank says, “The real estate business is like a roller coaster so when we can we like to save a lot of money. You never know what the next year is going to bring, so we have to be prepared for the worst.” So do people in our society make more money in a good economy? Yes!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! While during this project I learned to think outside the box and find a fun and creative way to prove my point. I look forward to doing similar projects to this one in the future.
