How to Use

This graphing calculator allows you to visualize mathematical functions instantly. Here's how to use it:

  1. Enter Function: Type your equation in the "f(x) =" box. Use x as the variable.
  2. Adjust Range: (Optional) Set the minimum and maximum values for both X and Y axes to zoom in or out.
  3. Plot: Click "Plot Graph" to render the function.
Supported Syntax examples:
  • Algebraic: x^2, x^3 - 2*x, 1/x
  • Trigonometric: sin(x), cos(x), tan(x)
  • Log/Exp: log(x), exp(x)
  • Roots: sqrt(x)

Frequently Asked Questions

The graph is interactive! You can click and drag to pan around the coordinate system. To zoom in or out, simply use your mouse scroll wheel while hovering over the graph area. If you're on a mobile device, you can use pinch-to-zoom gestures.

This calculator supports a wide range of functions including:
  • Standard operators: +, -, *, /, ^ (power)
  • Trigonometry: sin(x), cos(x), tan(x), asin(x), acos(x), atan(x)
  • Logarithms: log(x) (natural log), log10(x)
  • Other: sqrt(x), abs(x), exp(x), PI
Make sure to use parentheses () to group terms correctly, e.g., sin(2*x).

If the graph doesn't appear, check the following:
  1. Syntax: Ensure your equation is valid (e.g., use 2*x instead of 2x).
  2. Range: Check if your Y-axis limits (Y Min/Max) cover the function's output.
  3. Domain: Some functions (like log(x) for x < 0) are undefined in certain ranges and won't plot there.

Graphing Tips
  • Use * for multiplication (e.g. 2*x not 2x).
  • Use parentheses () to group terms clearly.
  • Domain errors (like dividing by zero) might create gaps in the graph.
