1. The problem is to understand how to use Desmos 3D to find three solutions to a given problem. 2. Desmos 3D is a tool for visualizing functions and equations in three dimensions, which helps in identifying points where equations intersect or satisfy certain conditions. 3. To find three solutions, you typically need to set up your equations or functions in Desmos 3D and look for points where they intersect or meet the criteria. 4. Important rules include understanding the variables involved, setting the correct domain and range, and using features like intercepts and extrema to locate solutions. 5. For example, if you have three equations, you can input them into Desmos 3D and visually inspect or use the tool's features to find the three points where all equations are satisfied. 6. Desmos 3D does not automatically solve equations but provides a visual aid to identify solutions. 7. Practice by plotting simple systems and gradually move to more complex ones to get comfortable with the interface and solution identification.
