Desmos Graphing Calculator

1. Download the app from your device store or open desmos.com, and optionally create a free account to save and sync your graphs. 2. Enter expressions in the left expression list to plot functions and inequalities, and add sliders by typing variables to explore parameter changes. 3. Use tables for data entry and regression, switch to geometry mode for constructions, and use the scientific calculator for advanced calculations. 4. Adjust graph settings for axes, grid, and angle units, then save, export as an image, or share a link; teachers can assign activities through Desmos Classroom.
