1. What is Desmos Graphing Calculator?

Desmos is an advanced graphing calculator implemented as a web application. It allows users to plot functions, create tables, add sliders, animate graphs, and more - all for free.

2. How to Use This Calculator

Basic Usage:

1. Enter a function in the "Function 1" field (e.g., x^2 + 3x - 2)
2. Optionally enter a second function to compare
3. Set the viewing window (X and Y min/max values)
4. Click "Graph" to display the function(s)
5. Use "Reset" to clear all inputs

3. Supported Functions and Syntax

Supported Operations:

• Basic arithmetic: +, -, *, /, ^ (exponent)
• Trig functions: sin(x), cos(x), tan(x), etc.
• Logarithms: log(x), ln(x)
• Square roots: sqrt(x)
• Absolute value: abs(x)
• Constants: pi, e

4. Tips for Effective Graphing

Best Practices:

• Start with default window (-10 to 10) and adjust as needed
• For trigonometric functions, use radians mode
• Use parentheses to clarify order of operations
• Zoom in/out to see different aspects of the graph

5. Frequently Asked Questions (FAQ)

Q1: Can I graph parametric equations with this?
A: This simplified version supports only y = f(x) functions. The full Desmos calculator supports parametric equations.

Q2: How do I find the intersection points?
A: In the full Desmos calculator, you can click on intersection points. Here, you'll need to estimate visually.

Q3: Can I save my graphs?
A: This version doesn't support saving. Use the official Desmos website for persistent graphs.

Q4: Why isn't my function graphing correctly?
A: Check your syntax - make sure all parentheses are closed and operations are properly formatted.

Q5: Can I plot data points?
A: This simplified version focuses on function plotting. The full Desmos calculator supports data tables.
