Graphing calculator
New here? Use Trace to step along a curve,Value / Zero / Min / Max / Intersect to read it precisely, andBox to drag-zoom into a region — everything undoes with the ↶ button or Ctrl+Z.
Drag to pan, scroll or pinch to zoom, or use Box to drag-zoom into a region. Enter a function as Y1 to get started.
Reference prior terms as u(n-1), v(n-2), etc.(nMin+1)= only matters for formulas that reach back two terms, like Fibonacci — leave it blank otherwise.
Reads from the L1-L6 lists you enter in Tools → Lists & Stats, plus RESID once a regression has populated it (for a residual plot). Turn a plot on, then pressZoomStat above to fit the window to its data.

LinRegTTest
Uses L1/L2 from Tools → Lists & Stats. Tests H0: slope = 0 (no linear relationship).
Quadratic: ax² + bx + c = 0
Cubic: ax³ + bx² + cx + d = 0

What is the TI-84 Plus CE calculator online?
It's a free web app modeled on the TI-84 Plus CE — the current-generation Texas Instruments graphing calculator with a color screen and MathPrint-style display — so the layout, function set, and workflow carry over directly if you already know the physical device. Type an expression, hit Enter, and switch between Calculator, Graph, Tools, and Programs modes with the same buttons you'd expect on a TI-84 Plus CE. It runs entirely in your browser, with nothing to install and no account to create.
What can it do?
- Function, parametric, polar, and sequence graphing with pan, zoom, and trace
- Exact fraction display, trig (inverse and hyperbolic), logs, and degree/radian/gradian modes
- Matrices, statistics, distributions, hypothesis tests, and an equation solver
- Finance (TVM Solver) and unit conversion tools
- Saved calculation history, variables A–Z, and Ans, restored automatically on your next visit
- Full keyboard support and screen-reader accessibility
How is it different from a real TI-84 Plus CE?
It's an original web app that reimplements the TI-84 Plus CE's functions in code — not a ROM emulator, and not affiliated with or endorsed by Texas Instruments. That means there's no firmware to run and no ROM to provide: it just works, in any browser, the moment you open the page.
Need the full syntax reference and keyboard shortcuts? Check the documentation. Curious how the TI-84 Plus CE compares to the original TI-84 and TI-84 Plus, or to the simpler TI-30XS? Read the TI-84 family history or compare it to the TI-30XS.
Frequently asked questions
Is this a real TI-84 Plus CE, or an emulator?
It's an original web app inspired by the TI-84 Plus CE's layout and workflow — not a ROM emulator and not affiliated with Texas Instruments. It runs entirely in your browser, with no download or install.
Does it support fractions, trig, and logs like a real TI-84 Plus CE?
Yes — exact fraction display, degree/radian/gradian trig with inverse and hyperbolic modes, log and ln, scientific and engineering notation, and more, all matching the TI-84 Plus CE's core function set.
Can I graph on this TI-84 Plus CE calculator?
Yes — switch to Graph mode for function, parametric, polar, and sequence graphing with pan, zoom, and trace, plus a Tools mode for matrices, statistics, distributions, and an equation solver.
Is my history and variable storage saved between visits?
Yes — your calculation history, stored variables (A–Z), and last answer are saved locally in your browser and restored automatically the next time you open the calculator.
Do I need to download anything to use this TI-84 calculator online?
No — it runs entirely in your browser on any device with an internet connection, with no install, account, or purchase required to use the full TI-84 Plus CE feature set.
How do I graph a function on this TI-84 Plus CE calculator?
Switch to Graph mode, enter your function, and it plots automatically with pan, zoom, and trace — the same workflow as pressing Y= and GRAPH on a physical TI-84 Plus CE. Parametric, polar, and sequence graphing are also supported.
Does this TI-84 Plus CE calculator work on Chromebooks and school laptops?
Yes — it's a web app, not a program you install, so it works on any Chromebook, school-managed laptop, tablet, or phone with a browser, even where software installs are locked down.
