How to Use the Desmos Graphing Calculator

Basic Graphing

  • Graph a function: Type an equation like "y = 2x + 1" in the expression list
  • Graph multiple functions: Add new expressions by clicking "+" or pressing Enter
  • Change the display window: Use the zoom buttons or click and drag to pan
  • Hide/show a graph: Click the colored circle next to an expression

Advanced Features

  • Create a slider: Define a variable and add a range, e.g., "a = 1" then click on it
  • Plot points: Enter points as (x,y) coordinates or create a table
  • Create a table: Click the "+" button and select "table"
  • Add notes: Click the "+" button and select "note" to add explanatory text
  • Find intersections: Click on a point where two curves intersect

Example Expressions

  • Linear function: y = mx + b (e.g., y = 2x + 3)
  • Quadratic function: y = ax² + bx + c (e.g., y = x² - 4x + 4)
  • Trigonometric function: y = sin(x) or y = cos(x)
  • Exponential function: y = a·eᵏˣ (e.g., y = 2e^(0.5x))
  • Parametric equations: (x(t), y(t)) (e.g., (cos(t), sin(t)))
  • Inequalities: y > x² or y ≤ 2x + 1

Applications of Graphing Calculators

Education

Students and teachers use graphing calculators to visualize mathematical concepts, from basic algebra to calculus and beyond, making abstract ideas more concrete and understandable.

Data Analysis

Scientists and researchers plot and analyze data, fit curves to data points, and visualize trends and relationships between variables.

Engineering

Engineers model physical systems, analyze performance curves, and visualize design constraints and optimization problems.

Economics and Finance

Economists and financial analysts graph supply and demand curves, visualize economic models, and forecast financial trends.

Tips for Effective Graphing

1

Adjust Your Window

Make sure your viewing window captures the important features of your graph. Use the zoom tools to focus on areas of interest.

2

Use Color Strategically

Assign different colors to related functions or to highlight important elements of your graph.

3

Add Labels and Notes

Include clear labels and explanatory notes to make your graph more informative and easier to understand.

4

Use Sliders for Exploration

Create sliders for parameters to explore how changes affect your graphs dynamically.
