![]() Here, it's pretty cool that there's an animating slider that tracing along each path - but I don't feel like it is significantly better than a static dashed curve (one at a time) and having the students create a solid curve to match. Side thought: when building lessons in Desmos, I'm constantly having to wrestle with "cool" ideas that are only cool because I know how the graph was built. No real mathematical thought, apart from "it's going up and down, let's try cosine", and in a class context the students will have already been primed to expect that kind of function anyway. But instructionally, I'm guessing your learning goal here is something like "use key features of sinusoidal curves to write equations" - and I didn't need to attend to that at all! All I did was type in y=cos(x) for the first line, saw immediately that the purple comet didn't follow that path but the green one did so I just pasted cos(x) into the green line. So that's kind of a bummer, just usability-wise. ![]() Review trigonometry concepts and learn about the. ![]() If I want to focus on just the purple comet, I have to wait an entire cycle (and potentially forget about whatever I had noticed the first time through). Sine and cosine are basic trigonometric functions that are used to solve for the angles and sides of triangles. My biggest concern is the four-in-one auto-playing animation. Write an equation for each colors' path." ![]() Maybe instead: "Watch the colored points move along their paths. "Identify each path by color" makes me think the expected responses are "this path is green that path is red". The instructions don't really work for me. You should know the values for sin and cos for angles of 0, 30, 45, 60, and 90 and then, by the symmetry of. You can either create a class code, and give that link to your instructor, or give them a link to the published activity and ask them to click the Student Preview button - or click on the first screen yourself, and give them that link: it'll take them directly to the student preview ( demo). Depends on how accurate you want the graph really. ![]()
