### π Introduction to the Decimals Graphing Calculator

This paragraph introduces the Decimals Graphing Calculator, a tool included in selected Cambridge Max products. It explains how to launch the calculator from the unit section by clicking on the Desmos graphing calculator icon in the toolbar. The user can reposition the calculator, go full screen, and use various features such as hiding the input section, zooming in on the coordinate plane, and adjusting settings like projector mode, grid lines, axis numbers, and scale. The paragraph also covers the input section where users can type in functions, expressions, coordinate points, or tables. Two methods for entering data are highlighted: directly typing into the expression fields or using the plus sign to add new ones. The video script also mentions how to correct errors in notation and how to add labels and change settings for coordinate points.

### π Exploring Features and Functions of the Graphing Calculator

The second paragraph delves into the use of the graphing calculator, starting with the input of coordinate points and the automatic update in the coordinate plane. It introduces the slider feature, allowing users to adjust the value of a variable and see the changes reflected in real-time. The paragraph also demonstrates how to create animations by adjusting variable values over time. The discussion moves on to linear equations, showing how to input them and view their representation on the coordinate plane, including identifying and marking intercepts. The use of sliders and lists of values to dynamically update expressions is also covered. The paragraph concludes with the benefits of using function notation, which allows for easier evaluation of expressions for specific values and the creation of tables of values that update automatically across the calculator.
