For example, the head of the elephant was made using a quintic function because we needed a function that would provide a good number of inflection points. To create the kinds of curves we needed in our images we planned on incorporating certain types of functions. We then began using Desmos to graph out our pictures. We first found pictures of the Tufts logo and elephant to model our drawings after. Desmos is free and very easy to use, but a graphing calculator could also be used. We decided to use the online graphing tool Desmos to play with our functions until we could decide on the final equations. Both pictures are very difficult and require a lot of functions, but we wanted to create pictures that would display the full effect of the project. We decided to draw out an elephant and the Tufts logo. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.

How can I move, change, or resize functions to fit my drawing? Explore math with our beautiful, free online graphing calculator.Students would also use limits to plot specific sections of their functions. Explore math with our beautiful, free online graphing calculator. Graphing a Picture (with Trig) I was inspired by Epsilon-Delta to assign my PreCalc students a project to create a picture using graphs. The students would also interactively learn how to scale and translate functions as they needed to move and resize plots. We decided we would have them draw out a picture using functions and this would challenge the students to choose what functions would best draw the picture. We wanted the students to have to play around with various types of functions and see how functions change depending on how you change coefficients within an equation. Learn how to translate and scale functions.Interact with various types of functions.To view our creations on Desmos, click on either of two graphs below. We utilized the online graphing tool Desmos to plot out our functions before hand drawing everything. We drew out an elephant using 15 different functions and the Tufts logo using 87 functions. Explore math with our beautiful, free online graphing calculator. Students can use a variety of different functions however many times they want, but they must use at least five types of equations from the following list:Īuthors: Rose Solow and Orian Sneor Final Project Explore math with our beautiful, free online graphing calculator. Multiple functions of different types should be utilized within the project and a list of all of the functions used should be included. Students should choose some image to recreate and then use various different functions to graph out the picture. (not remembering to whom to give credit, sorry).Create a visual picture by graphing a series of functions. Desmos Graphing Calculator, drawing lines overtop the photograph to prove. They are a work in progress Looking forward to seeing them completed. Transfer To transfer knowledge, students. I did give a little hint at animating them but I didn't require it. DecemHere are some updates on a few pictures using equations of lines. Then, I took their link and pasted it into my own desmos activity builder (with a little help from twitter - paste it into an equation window in the graph window. I created a google doc and had them paste their desmos link in there. They did not have to print out the picture or the equations. I didn't teach conics this year, so less emphasis on that although they could/should include some of those equations because they did them in geometry last year. This year, I had them make original pictures. They had to print out their picture and color it, put it on construction paper and print out all their equations (usually 100-600 equations, although I didn't put a number on them) and then their algebra work to solve the systems. Then, they would have to do out two systems of equations - one conic and non-conic and 2 conic intersections. I used to have the students find a picture, drag it in and write the equations to make the picture. I also wanted to use just tech and not paper. Explore math with our beautiful, free online graphing calculator. However, now there are so many online, I wanted to remove opportunity to cheat so we made a few changes. I have had my Algebra 2 students make an art project using Desmos for a few years now.
