HelloMy name is Ryan and I use desmos frequently in my classroom. I was wondering if there is any way to place imaginary numbers or complex numbers into desmos like you can with the TI calculators when you change the mode from real to a + bi? If so this would be very helpful for those students who do not have calculators of their own to work at home on our remote days or for homework.
You can make Desmos activities that handle specific uses for complex numbers - it would be quick to make an activity that adds complex numbers, for example - or to avoid reinventing the wheel you can direct your students to other online resources like Symbolab or WolframAlpha.
If you have a calculator with characters that are one inch or higher, or if your calculator has a raised display that might be visible to other test takers, you will be seated at the discretion of the test coordinator.
Take and manage screen captures from your connected graphing calculator quickly and simply. The Screen Capture workspace also enables you to convert images to be used as a background on your calculator.

A scientific calculator (must not have unapproved features or capabilities; see list of unapproved calculators and technology) or graphing calculator are recommended; a four-function calculator is allowed but not recommended.
Graphing calculator with statistical capabilities. Nongraphing calculators are permitted if they have the required statistics computational capabilities described in the AP Statistics Course and Exam Description. (effective Fall 2020)
*Graphing calculators with the expected built-in capabilities for AP Calculus are indicated with an asterisk. See the AP Calculus AB and BC Course and Exam Description for details. However, students may bring any calculator on the list to the exam; any model within each series is acceptable. Only approved graphing calculators from the list are permitted for AP Calculus Exams.
Calculators are not allowed for any other AP Exams, including Computer Science A and Computer Science Principles, unless a student has an approved accommodation for use of a 4-function calculator.
This list will be updated as necessary to include new approved calculators for 2025 AP Exams. Check this list periodically, and before the administration of the exams, to ensure that students have the most up-to-date information.
* Graphing calculators with the expected built-in capabilities for AP Calculus are indicated with an asterisk. See the AP Calculus AB and BC Course and Exam Description (effective Fall 2020) for details. Only approved graphing calculators from the list are permitted for AP Calculus Exams.
This list only includes approved graphing calculators. There is not an approved list of scientific (nongraphing) calculators. Note that scientific (nongraphing) calculators must not have unapproved features or capabilities.
Proctors are required to check calculators before the exam. Therefore, it is important for each student to have an approved calculator. Calculators may not be shared, and communication between calculators is prohibited during the exam.
I am working on a graphing calculator (you know, one where you type in a formula, let's say x^2 and you get the graph of that function). The problem I am having is how to offset and scale the view of graph as to show the interesting section of the function.
I have exhausted all the 'simple' ideas I have had. Let me show some example:- sin(x) => interesting section is between y = [-1,1] and offset (0,0)- x^2 => interesting section is between y = [0, 100] and offset is (0,0). (100 has been picked arbitrarily)- 100x^2 - 10000 => y = [-10000, 100*] and offset is (-10000, 0)
I figured I could assign a 'range' and 'offset' for each type of function and create some math to add/multiply/etc these range together the same way a result would be calculated. However, that requires 'creating' some math and the potential for well hidden logical flaws is way too high.
There are obvious edge cases: the function may have no, one, or infinitely many roots. The function may have no maximum or minimum. I'm not really sure how you can detect these cases, but you might want to build in limits to steps (1) and (2), like find the first N roots or the first N extrema, counting out from 0. Another limit might be making sure your excursion on one axis is never more than N times the excursion on the other axis.
Two interesting points of most common graphs are the origin of the coordinate system (for orientation) and the y-intercept of the function, which is easy to compute. Hence, I'd choose the scale such that both the origin (0,0) and the y-intercept (0,y0) are visible, plus some padding, i.e. the interval [-y0 - y0/5; y0 + y0/5]. If origin and y-intercept happen to be close or even the same, I'd choose a visible interval of, say, [-5; 5].
The rationale behind this is that a well-formulated function is supposed to have its interesting part somewhere near the origin, or at least near the y-intercept. If it doesn't, you simply can't tell what the user wants to see, so he shall take care of that himself.

You are awesome! I went to geek squad and to a computer tech store and no one could help me figure this out. It has taken over a month. I ran across your site about an hour ago and it took me a little to work out the kinks but I got it!!!! I am so grateful!
Thank you so much for the tutorial, this greatly helps me in more ways than cheating, it is nice to be able to have notes to refer to without having to spend countless hours typing them in with the calculators keyboard. Very much appreciated!
I downloaded as recommended. I ordered my usb cords from Amazon. I entered my notes while I waited for Amazon to deliver the cords. Just got it today. Finished the transfer today. It looks great on my calculator. My finance test is tomorrow. Thank you SO much! This will really help me out.
We loan out a wide range of technology items from the 2nd floor circulation desk, the 3rd floor technology loan desk, and the self-service kiosks with the support of the Baruch Student Technology Fee. While most items have short loan periods, selected items (such as Chromebooks and graphing calculators) can be checked out for the entire semester.
Only currently enrolled Baruch students who have their student IDs with them may check out any of the items on this page. Students in the CUNY School of Professional Studies may borrow designated selected laptops.
A graphing calculator (also graphics calculator or graphic display calculator) is a handheld computer that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. Most popular graphing calculators are programmable calculators, allowing the user to create customized programs, typically for scientific, engineering or education applications. They have large screens that display several lines of text and calculations.
Casio produced the first commercially available graphing calculator in 1985. Sharp produced its first graphing calculator in 1986, with Hewlett Packard following in 1988, and Texas Instruments in 1990.[citation needed]
Some graphing calculators have a computer algebra system (CAS), which means that they are capable of producing symbolic results. These calculators can manipulate algebraic expressions, performing operations such as factor, expand, and simplify. In addition, they can give answers in exact form without numerical approximations.[5] Calculators that have a computer algebra system are called symbolic or CAS calculators.
Many graphing calculators can be attached to devices like electronic thermometers, pH gauges, weather instruments, decibel and light meters, accelerometers, and other sensors and therefore function as data loggers, as well as WiFi or other communication modules for monitoring, polling and interaction with the teacher. Student laboratory exercises with data from such devices enhances learning of math, especially statistics and mechanics.[6]
Since graphing calculators are typically user-programmable, they are also widely used for utilities and calculator gaming, with a sizable body of user-created game software on most popular platforms. The ability to create games and utilities has spurred the creation of calculator application sites (e.g., Cemetech) which, in some cases, may offer programs created using calculators' assembly language. Even though handheld gaming devices fall in a similar price range, graphing calculators offer superior math programming capability for math based games. However, for developers and advanced users like researchers, analysts and gamers, third-party software development involving firmware modifications, whether for powerful gaming or exploiting capabilities beyond the published data sheet and programming language, is a contentious issue with manufacturers and education authorities as it might incite unfair calculator use during standardized high school and college tests where these devices are targeted.
Most graphing calculators, as well as some non-graphing scientific calculators and programmer's calculators can be programmed to automate complex and frequently used series of calculations and those inaccessible from the keyboard.
The actual programming can often be done on a computer then later uploaded to the calculators. The most common tools for this include the PC link cable and software for the given calculator, configurable text editors or hex editors, and specialized programming tools such as the below-mentioned implementation of various languages on the computer side.
