1.Parent Functions: Parent functions are functions that can determine the "shape" of certain graphs. Below is a slideshow with an example and description for each parent function. Pay attention to the left sidebar to see which equation is being displayed and either click the arrows in the top right or click the thumbnails at the bottom to navigate the functions. 2.Changing Equations: You can also transform functions by changing them. Once again, below is an example of some types of transformations, each a caption explaining it. To use Desmos, you first need to actually go to the website. Either use desmos.com or desmos.com/calculator to skip right to the graphing page of the website. Here you can enter equations you want on the side. There are also more features found by click the plus icon, which includes more options to add to your graph. This includes adding a table, which can be used to create a line. Just type in points on the line according to the line you want. For example if you have line y=2x, then on the table you could have y=-4; x=-2 and y=4; x=2 to create a portion of that line.
You can also easily find intersection points on line in Desmos. Whenever a line intersects another line, the x-axis or the y-axis, they are marked by a grey dot that will tell you exactly what coordinates they intersect when you hover over it. If you want specific dimensions to view your graph, Desmos supports that too. Just lick the wrench icon in the top right and then edit the maximum and minimum for the x-axis and the y-axis. If you want to share your graph there are multiple ways you can do that. You could click the share graph button in the top right, then give the link to the person, or you can use the print-screen button to copy your computers screen and get a picture of the graph you can send to someone. If your looking at line and want to figure out it's equation, remember most linear lines have 2 parts, a slope and the x intercept, represented in the expression y=mx+b. in this case the slope is m and the x-intercept is b. To find the slope of graph pick two points and then use rise divided by run. This will tell you the slope of line. The x-intercept is simply the point where the line intercept the x-axis. then you can plug those numbers into y=mx+b and get the equation of the line. For example, in the line below you can see that the line rises by 2 for every time x goes one unit, meaning the lines slope is 2. You can also see that the x-intercept is 2. So, it's equation is y=2x+2. Getting Gmath: Have a google doc open then click "Add-ons" near the top. The click "Get add-ons" and then search for the g(Math) add-on. From there just click, it then click the "+ Add" button.
Inserting an equation/Expression: Go Add-ons>g(Math)>Create math expressions. Now a sidebar should open up on the side of your screen. You can use the simple setting to easily create expressions, but if you want more complicated expressions click the advanced option near the top and then use the LaTeX editor. Select the x^a button to put in more complicated expressions, then replace the variable with what you want in the editor. For example if you want to add a faction to your equation just click the x^a button then click the one that looks like a faction with x and a, and then edit the code that appears so the variable are what you want. Handwriting Entry: To put in an expression in handwritting go Addon-ons>g(Math)>Create a handwriting entry. Now a box should appear on screen where you can write what you want. When you're finished you click the button in the lower left to put the equation in the doc. Graphs: To create a graph go Add-ons>g(Math)>Create a graph, then a side bar should appear. Put in the expression you want to make in the box near the top of the sidebar. You can also change the scale by changing the values in the boxes below your equation. Once you are done you should probably check it by clicking the preview button, and if your happy with what you see, click the blue insert into doc button.
Today in class my group edited our Prezi based off suggestions and added a video to our slide. We also added some rotation to make presentation more interesting.
Adding rotation is very simple, when you hover your mouse over the corner of a frame a small circle will appear. You can drag it change the rotation of everything inside your frame. When you present the camera will smoothly zoom in the changed rotation. We also added a video, wich was as simple as getting a Youtube link and putting that into the "Insert Youtube video" feature. Being very familar with Prezi maybe useful in the future. It's a relatively popular service so I might be required to use it in the future. Two days ago our group added pictures, music and work cited to our project. This was done using Prezi and Noodletools. We also added a few extra things like a video and rotation.
We added audio to our Prezi (The national Anthem of New Zealand) this was fairly simple, you just need the file, then click "Insert Music" under the "Insert Menu." We also added the work cited, which was done by exporting our Noodletools sources into a PDF then adding the papers to the Prezi. Finally, we added picture which was done by pressing "Insert picture" and selecting it from our computer. Knowing how to use these extra feature of Prezi maybe useful in the future if I ever have to make one. The music feature could be used for voice-over as well. Today in class our group used the Databases available to students to collect information on New Zealand. We collected the information into Noodle Tools note cards and then organized and color coded them. Finally we started to work on our Prezi presentation, but we didn't get much farther then sharing the project.
We learned how to use the tool Prezi. It works somewhat similar to a standard slideshow, in that way it is organized. You have to place frames over a large image, when you get to that part in the slideshow the camera will zoom in where ever you placed it. Inside the frame you can put pictures, words, etc. so that when the camera zooms in your audience can see what it says. Knowing how to use Prezi, Noodle tools and Databases maybe useful in the future as they are common things to know when researching and presenting a topic. I now have a good knowledge of how to use them and won't need to be taught again in the future. In class we added all our information to our Prezi. We got the information from CultureGrmas, transferred it to Noodletools, then transferred that in our words to our Prezi. We also added music and pictures from CultureGrams and Britannica ImageQuest.
Using Prezi is fairly simple, you just need to create frames then add information and pictures. Personally, I prefer to use the separate slides I don't have to worry about space or overlapping frames, but it isn't that annoying. Using Prezi and databases maybe useful in the future if I ever need to collect for a project. I may use Prezi in the future for another project, it gives projects a fairly smooth and polished look that google slides presentations may not have.

I picked this because I really wouldn't mind people using it for whatever they want. It didn't take much work to create this image, so if it helps someone out, I think that's the best possible outcome! Today in class our group learned about copyright law from a playlist.
Our group learned exactly how copyright law works. It gives the creator of a work the exclusion right to copy, distribute or display their work. Unless it has expired, you have permission, or it's under fair use. Fair use allows you to use a work as long it isn't for profit and it's for specific purposes. Knowing copyright might be useful in the future. It will insure that I use everything I find without stealing it. |
