TI-84 Graphing Calculator

Online TI-84 Graphing Calculator

A full-featured graphing calculator inspired by the TI-84 Plus CE, running entirely in your browser. No downloads or plugins required. Enter equations in the Y= editor, view real-time graphs with zoom and trace, generate value tables, and perform scientific calculations.

Graphing Features

• Y= editor supporting up to 4 simultaneous equations
• Polynomials, trigonometric, exponential, logarithmic, and absolute value functions
• Trace mode to read exact coordinates along any curve
• Adjustable window settings (Xmin, Xmax, Ymin, Ymax, scale)
• Zoom in, zoom out, standard zoom, and trig zoom presets
• Table view showing computed x/y values

Scientific Calculator

• Trigonometric functions: sin, cos, tan and their inverses
• Logarithmic functions: log (base 10) and ln (natural log)
• Powers, roots, absolute value, and cube root
• Constants: pi and e
• Radian and degree mode toggle
• ANS recall and multi-line history

How to Use

1. Use the Calculator tab for arithmetic and scientific computations.
2. Switch to Graph to enter Y= equations and visualize them on a coordinate plane.
3. Enable Trace mode and use arrow keys to follow curves and read coordinates.
4. Open the Table tab to see a value table for all active equations.
5. Press 2ND for inverse trig functions and alternate key functions.
