Why use this TI‑84 online calculator?
- Fast & free: No downloads, no sign‑in.
- Graph multiple functions: Color‑code, toggle visibility, and export PNG.
- Trace + table: Read exact values or generate a table and export CSV.
- DEG/RAD & exam mode: Match classroom settings and disable exports in exams.
- Mobile‑friendly: Works great on phones and tablets with pinch/zoom and drag to pan.
Supported syntax
Functions: sin, cos, tan, asin, acos, atan, ln, log (base‑10), sqrt, abs, exp, min, max, pow. Constants: pi, e. Use ^ for powers, e.g., x^2. Switch between degrees and radians with the toolbar toggle.
How to graph
- Click + Add function and enter an expression such as
sin(x)orx^2 - 3x. - Press Plot. Use the mouse (or touch) to pan and the scroll wheel to zoom.
- Use Trace to see the x and y values under the cursor.
Frequently asked questions
Is this the same as a physical TI‑84?
It is a web‑based simulator inspired by the TI‑84 experience. It covers common graphing features but isn’t official TI software.
Can I share a graph?
Yes. Use the Share button—the page URL updates with your functions and view so you can copy and send it.
Why does sin(30) show different results?
Ensure DEG is selected for degrees. Switch to RAD for radians.
