📖 What is a Graph Calculator?
Understanding Function Visualization
A graph calculator is an essential mathematical tool that transforms abstract equations into visual representations. By plotting functions on coordinate axes, you can:
🎯 Identify Key Features
- Roots/Zeroes: Where the function crosses the x-axis
- Intercepts: Where it crosses the axes
- Asymptotes: Lines the function approaches but never touches
- Turning Points: Local maxima and minima
📈 Understand Behavior
- Increasing/Decreasing: Where function values rise or fall
- Concavity: Whether the curve bends up or down
- Periodicity: Repeating patterns in trigonometric functions
- Symmetry: Even, odd, or periodic symmetry

❓ Advanced Calculator FAQ
How do parameter sliders work?
Click "Add Parameter Slider" and define a variable (like 'a', 'b', or 'k'). Use it in your function (e.g., "a*x^2"). The slider will let you animate how changing the parameter affects the graph in real-time. Perfect for understanding transformations!
How does intersection detection work?
Click "Find Intersections" to automatically detect where your plotted functions cross each other. The calculator uses numerical methods (Newton-Raphson) to find precise intersection points with coordinates displayed on the graph.
Can I share my graphs with others?
Yes! Click "Share URL" to generate a unique link that encodes your current graph state (functions, ranges, parameters). Anyone with the link can view and interact with your exact graph setup. Perfect for teachers sharing examples with students!
What regression types are supported?
We support linear (y = ax + b), quadratic (y = ax² + bx + c), exponential (y = ae^(bx)), and power (y = ax^b) regression. Click "Regression Analysis", enter your data points, choose a model, and we'll find the best-fit curve with R² values and plot the result.
Is this really as good as Desmos?
We've implemented the core features that make Desmos great: real-time plotting, parameter sliders, intersection detection, and beautiful LaTeX rendering. While Desmos has more advanced CAS features, our calculator excels at being 100% free with no ads, no sign-up, and integrated with our complete calculus learning platform.
