TI 84 Calculator Online FAQ
Know what this tool can do before you start.
Is this an official TI-84 calculator emulator?
No. This is an independent, browser-based scientific calculator and graphing learning tool. It does not reproduce every feature, screen, app, or behavior of a physical TI-84 calculator and is not affiliated with Texas Instruments.
Can I graph equations online?
Yes. Open Graph mode, enter a supported function using x, and select Plot. The graph panel samples the function over a coordinate range. Complex or unsupported syntax may not plot correctly.
Which functions are supported?
The current calculator supports basic arithmetic, parentheses, powers, square roots, absolute values, trigonometric functions, logarithms, constants pi and e, and a recent calculation history. It is not a symbolic algebra system.
Does angle mode matter?
Yes. Trigonometric calculations can use radians or degrees. Check the displayed angle mode and make sure it matches your assignment before interpreting a result.
Can I use this during an exam?
Do not assume this website is allowed in an exam. Calculator rules vary by school, test, and testing platform. Check the current policy from your instructor or exam provider.
Are my calculations sent to a server?
The calculation engine on this starter site runs in your browser. Hosting, analytics, advertising, embedded services, and future integrations may process data separately; review the published privacy policy for the live website.
