The Graph Calculator helps you plot mathematical equations visually. You can enter equations using x, such as x*x, Math.sin(x), Math.cos(x), or x*x*x.
Introduction
The Graph Calculator is a useful math tool for plotting equations and understanding the shape of functions. It helps students, teachers and learners visualize mathematical expressions.
What is a Graph Calculator?
A Graph Calculator is an online tool that converts mathematical equations into a visual line graph. It plots x and y values so users can understand how the function behaves.
Supported Equation Examples
x*x → Quadratic Function
x*x*x → Cubic Function
Math.sin(x) → Sine Function
Math.cos(x) → Cosine Function
Math.tan(x) → Tangent Function
How to Use the Graph Calculator
Enter a mathematical equation using x.
Use JavaScript math syntax such as Math.sin(x) or Math.cos(x).
Click the Plot Graph button.
The graph will appear below the input section.
Your equation will be saved in browser history.
