Online Graphing Calculator (TI-84 Style)

Enter a function to plot the graph instantly.

Supported: +, -, *, /, ^, sin, cos, tan, log, sqrt, abs, pi, e

How to Use This Online Graphing Calculator

This tool mimics the functionality of a standard TI-84 graphing calculator. It allows you to visualize mathematical functions directly in your browser without downloading any software. Whether you are checking homework or exploring complex calculus concepts, this tool provides instant visual feedback.

Step-by-Step Instructions

  1. Enter the Function: In the f(x) field, type the equation you want to graph. Use standard mathematical notation. For example, type x^2 for a parabola or sin(x) for a sine wave.
  2. Set the Window (X and Y Range): Just like a physical calculator, you can zoom in and out by adjusting the X Min, X Max, Y Min, and Y Max values. The default view is from -10 to 10 on both axes.
  3. Draw Graph: Click the "Draw Graph" button to render the function. The graph will appear on the coordinate grid below the controls.

Supported Mathematical Functions

This calculator supports a wide variety of operations and functions commonly found in algebra and trigonometry:

  • Basic Operations: Addition (+), Subtraction (-), Multiplication (*), Division (/), and Exponents (^).
  • Trigonometry: Sine (sin), Cosine (cos), Tangent (tan).
  • Logarithms: Natural log (ln) and Base-10 log (log).
  • Other: Square roots (sqrt), Absolute value (abs), and constants like Pi (pi) and Euler's number (e).

Tips for Accurate Graphing

If your graph appears as a straight line or does not show up at all, check your window settings. If the Y-values of your function are very large (e.g., x^10), you may need to increase the Y Max value significantly. Conversely, if you are graphing very small numbers, adjust the window to show decimal ranges.
