Online Graphing Calculator

TI-84 Style Function Plotter

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

How to Use This Online Graphing Calculator

This tool mimics the functionality of a standard TI-84 graphing calculator, allowing you to visualize mathematical functions directly in your browser. To get started, enter your desired equation in the format f(x). For example, to graph a parabola, you might type x^2 or x^2 - 4.

Setting the Window (X and Y Axes)

Just like a physical TI-84, you can adjust the "Window" settings to zoom in or out on specific parts of the graph. Use the X Min and X Max inputs to control the horizontal range, and the Y Min and Y Max inputs to control the vertical range. Clicking "Graph Function" will redraw the plot based on these new boundaries.

Supported Mathematical Functions

This calculator supports a wide variety of operations commonly used in algebra and calculus:

  • Basic Arithmetic: Addition (+), Subtraction (-), Multiplication (*), Division (/)
  • Exponents: Use the caret symbol (e.g., x^2 for x squared)
  • Trigonometry: sin(x), cos(x), tan(x)
  • Roots & Logs: sqrt(x) for square root, log(x) for base-10 log
  • Constants: pi for π, e for Euler's number

Troubleshooting Graphs

If your graph does not appear, check the syntax of your equation. Ensure that you are using explicit multiplication (e.g., use 2*x instead of 2x). If the line appears broken or jagged, it may be due to asymptotes (like in 1/x) or the function reaching extremely high values within the current window.
