Online Graphing Calculator

Enter a mathematical function to visualize its graph instantly.

Use JavaScript syntax (e.g., Math.sin(x), Math.pow(x,2))

How to Use the Graphing Calculator

This tool allows you to plot mathematical functions directly in your browser. Simply enter the equation you wish to graph in terms of x. For example, to graph a parabola, you would enter x*x or Math.pow(x, 2). Adjust the X and Y axis ranges to zoom in or out on specific parts of the graph.

Supported Mathematical Functions

Because this calculator uses standard JavaScript math syntax, you have access to a wide range of functions. Here are some common examples:

  • Trigonometry: Math.sin(x), Math.cos(x), Math.tan(x)
  • Logarithms: Math.log(x) (natural log), Math.log10(x)
  • Exponents: Math.pow(x, 2) (squared), Math.exp(x) (e^x)
  • Constants: Math.PI, Math.E

Understanding the Coordinate System

The graph is plotted on a Cartesian coordinate system. The horizontal axis represents the independent variable (x), and the vertical axis represents the dependent variable (y) or f(x). By default, the view is centered at (0,0), but you can shift the focus by changing the minimum and maximum values for both axes.
