2D Function Grapher

How to use: Enter a mathematical expression in terms of x. You can use standard JavaScript Math functions (e.g., Math.sin(x), Math.cos(x), Math.pow(x, 2) or simply x^2). Adjust the axis ranges to zoom in or out.

Understanding the Graphing Calculator

This interactive tool allows you to visualize mathematical functions in a standard Cartesian coordinate system. Whether you are a student studying algebra or a professional analyzing data trends, plotting functions is essential for understanding behavior.

How to Plot Functions

To use the calculator, simply type your function using the variable x. For example, to plot a parabola, you would enter x^2. The tool automatically interprets standard mathematical notation. You can also use trigonometric functions like sin(x) or cos(x).

Adjusting the Viewport

The "X-Axis" and "Y-Axis" inputs control the zoom level of your graph. By decreasing the difference between the Min and Max values, you zoom in to see finer details. Increasing the range zooms out to show the broader shape of the curve. This is particularly useful for finding roots or intersections.

Common Syntax Examples

  • Linear: 2*x + 5
  • Quadratic: x^2 - 4
  • Exponential: Math.exp(x) or 2^x
  • Trigonometric: Math.sin(x) * x
