![]() ![]() Therefore, I would probably have to go back and re-shoot the entire video just to fix one mistake. However, if I was sharing a video with my students, I would not want them to be confused by a mistake on my part. This was a small mistake, so I just let it slide for the purposes of this assignment. Click an image to open that Desmos graph in a new tab. If you want to use the function in other parts, name the function r() instead of just r. To type, you can either type the word theta or find it in the alphabet keyboard within Demos. For example, when I re-watched the embedded video, I realized that I made a mistake at the 1:33 mark – I said the circle had radius 4 when I meant to say that it had radius 2. Many teachers have created activities for their classes using the calculator. To create a polar graph, type r equal to the function you want. One thing I don’t like about screencasting is how difficult it can be to fix mistakes. With inequalities, you can add colored shading to your Desmos graph. I am struggling with inequalities where the boundary is a vertical line. Its still a work in progress, but I’ve gotten pretty far. For example, if I want my students to know that the derivative of sin(u) is cos(u), but I don’t have time to show a formal proof in class, I could give them access to a screencast of me proving it. Hi, I am trying to have the CL read an inequality based on manipulating points on the graph. ![]() ![]() I could also use it show mathematical proofs for things that I don’t have time to prove in class. This is happening with all the other inequalities on screen 2. For example the inequality x + 2y < 100, a dotted line should go through the point (0, 50), instead it is going through (0, 49.5). In the future, I could see myself using a screencast to explain to students how to use technology, such as the Desmos graphing calculator or even certain functions on a Texas Instruments calculator. Hi I am trying to figure why the inequalities that appear in the table on screen 3 are graphing incorrectly. I was easily able to record my video and upload it to the UP media page. I thought using CaptureSpace was a fairly straightforward process, which isn’t how I normally feel after using a program for the first time. Desmos is great for graphing inequalities, especially when they. I used CaptureSpace to record an instructional video on how to graph inequalities with Desmos graphing calculator. Alternatively, we may use the Functions key in the Desmos keyboard to obtain the required functions. This video shows how to use graphing calculator to graph systems of inequalities. ![]()
