Feature	Description	How to Use	Benefits
Graphing Functions	Plot and visualize various functions, including linear, quadratic, trigonometric, and more.	Enter the equation directly into the input field. For example, type "y = x^2" to graph a parabola.	Instant visual representation of mathematical concepts, aiding in comprehension and problem-solving.
Plotting Points	Plot individual points on the coordinate plane.	Enter the coordinates in parentheses, such as "(2, 3)".	Visualize data, explore relationships between variables, and create geometric shapes.
Visualizing Algebraic Equations	Graph and analyze equations to understand their behavior and solutions.	Enter the equation in the input field, such as "x + y = 5".	Provides a visual interpretation of algebraic concepts, making them easier to grasp.
Adding Sliders	Introduce sliders to dynamically change variables and observe their effects on the graph.	Type a variable (e.g., "a") and set the range of values for the slider. Use the variable in your equation.	Enhances understanding of the relationship between variables and the function's behavior.
Animating Graphs	Animate graphs to visualize the evolution of functions over time or with changing parameters.	Use sliders with time-dependent equations, or create animations using multiple graphs.	Ideal for exploring dynamic mathematical concepts like projectile motion or wave functions.
Gridlines	Toggle gridlines on or off to customize the visual appearance of the graph.	Click the wrench icon in the upper right corner of the graph and adjust the grid settings.	Allows for cleaner graphs and better focus on specific features, as desired.
Graph Settings Menu	Customize the graph's appearance and behavior.	Click the wrench icon to access options for axes, grid, labels, and more.	Enhances readability and facilitates analysis.
Saving and Sharing	Save your graphs for later use and share them with others.	Use the "Save" button to create a shareable link or download the graph.	Enables collaboration, easy access to previous work, and the ability to share results.
Line Graph with Best Fit	Create line graphs and determine the best-fit line through a set of data points.	Enter the data in a table, and then use the appropriate syntax (e.g., y1 ~ mx1 + b) to find the best-fit line.	Useful for data analysis and identifying trends in data.
Restricting Domain and Range	Limit the portion of a graph that is displayed.	Use curly braces to define the desired domain or range (e.g., y = x^2 {0 < x < 5}).	Focus on the section of the graph most relevant to the task, or to define functions piece-wise.
Creating Notes	Add text annotations to your graphs to explain concepts or provide context.	Click the "Add Note" button and type in your text.	Makes graphs more informative and educational.
Organizing Lines into Folders	Group related expressions together for easy management.	Click the Add Folder button, name the folder, and drag and drop expressions into it.	Keeps complex graphs neat and orderly.
Sound in DesmosGraph	Add sound to graphs using the "tone" function.	In Desmos 3D and the geometry tool, use the tone function with frequency and gain as inputs.	Adds a new dimension to the graphs, making them more interactive.
Desmos Music Maker	Create music using Desmos.	Use mathematical functions to define notes, rhythms, and other musical elements.	Allows users to explore the connection between mathematics and music.
3D Spherical Plotting	Graph functions in 3D space.	Use the 3D calculator and enter equations or expressions in 3D coordinates.	Visualize complex functions, especially for students, and explore three-dimensional spaces.

Desmos is more than just a calculator; it's an interactive tool for exploration and discovery. One of the most powerful features of Desmos is its ability to create graphs from tables.

Whether you're creating a line graph with a best fit, exploring the relationship between variables, or simply plotting data, Desmos makes the process simple and intuitive. It is an invaluable tool for students, teachers, and anyone who wants to explore mathematics visually.

For those seeking more detailed guidance, the Desmos User Guide provides an efficient, illustrated overview of the basics. The graphing calculator page in the help center offers a comprehensive overview of all the features and options. The Desmos community is also active on subreddits, where users share their creations, ask questions, and engage in discussions about mathematical phenomena. Jennifer's written instructions provide specific guidance for screen reader users on how to create line graphs, ensuring accessibility for all.

The ability to tailor the appearance of your graphs is another key feature of Desmos. You have the option to turn the gridlines on or off, based on the type of graph you are trying to create. The grid is automatically shown on new graphs, but you can easily adjust it by clicking on the wrench icon located in the upper right-hand corner of the screen. If the grid checkbox is enabled, the grid lines will be visible, providing a helpful reference for plotting points and analyzing functions. The same tools can be utilized to customize your graphs to create a better presentation.

Creating a line graph with a best fit on Desmos is straightforward. Enter your data in a table format, and the calculator will allow you to determine the best fit line. This is particularly useful for data analysis and statistical applications. For those new to the platform, the basic steps involve entering your data points into a table and then using the appropriate syntax to determine the line of best fit. This process provides a visual representation of the data and allows for a better understanding of the relationship between variables.

Desmos isn't just about plotting points and drawing lines. Its about making math fun, accessible, and creative. It can streamline the process of learning and teaching math.
