How to Use the Online Graphing Calculator

This tool allows you to plot mathematical functions directly in your browser. Simply enter the equation you wish to visualize using the variable x, define your viewing window (X and Y axis ranges), and click "Draw Graph".

Supported Mathematical Functions

You can use standard JavaScript math syntax. To make it easier, the calculator automatically recognizes common abbreviations:

Basic Operations: +, -, *, /, and ^ for exponents (e.g., x^2).
Trigonometry: sin(x), cos(x), tan(x).
Other Functions: sqrt(x) for square root, log(x) for natural logarithm.
Constants: pi (≈3.14159) and e (≈2.71828).

Tips for Accurate Graphing

If your graph appears as a straight line or empty, your axis ranges might be too large or too small for the function. For example, if plotting x^2, setting the X range from -100 to 100 will make the parabola look very steep. Try a smaller range, such as -10 to 10, to see the curve more clearly. Always ensure your syntax is correct, particularly matching opening and closing parentheses.
