FAQ

1. Does the online TI-84 support graphing multiple functions at the same time?

Yes. You can enter several functions in the Y= menu (Y1, Y2, Y3, etc.). When you press GRAPH, the calculator will display all of them on the same coordinate plane. This is especialy useful for comparing equations, analyzing intersections, and visualizing relationships between functions.

2. Can I use it for regression and statistics calculations?

Absolutely. The STAT menu works exactly like the physical TI84. You can enter lists, run one-variable or two-variable stats, and perform regressions such as linear, quadratic, exponential, and power regression. The results are identical to a real TI-84 Plus.

3. Does the TI-84 calculator allow saving graphs or screenshots?

Some browser versions allow you to right-click and save the canvas or take a screenshot. While the emulator itself does not have a built-in “save graph” button, you can easily capture your graph using your device’s screenshot tool.

4. Can I use table mode (TABLE and TBLSET) in this calculator?

Yes. The TABLE and TBLSET functions work exactly like on the real calculator. You can set the starting value, the increment, and view x- and y-values for any function entered in the Y= menu. This is very helpful for homework and function analysis.

5. Does this TI-84 online version support angle mode changes (degree ↔ radian)?

Yes. You can switch between Degree and Radian modes in the MODE menu. Trigonometric functions will then calculate results according to the mode you selected.

6. Can I perform matrix operations such as inverse, determinant, or multiplication?

Yes. The MATRIX menu supports creating, edting, and performing all of these matrix operations.

7. Does the online TI-84 emulator support solving equations?

Yes. It allows solving linear, quadratic, polynomial, and trigonometric equations. You can use:

• The Equation Solver is under the MATH menu.

• Graph → CALC → Intersect for roots.

• Numeric solve methods via custom expressions.

8. Can I graph piecewise functions on the TI 84?

While the TI-84 doesn’t support an official “piecewise” input, you can graph functions piecewise by entering multiple conditions using the inequality and logic features. The online version supports this the same way the physical calculator does.

9. Can I store values and recall them later?

Yes. The STO→ key works normally. You can store values to variables (A, B, C, etc.) and recall them whenever needed, just like on a real TI-84 Plus.

10. Is it possible to do probability calculations such as nCr, nPr, or random numbers?

Yes. Under MATH ⇒ PRB, you can use:

• nPr

• nCr

• ! (factorial)

• random integers

• random decimals

11. Does the online TI-84 allow editing equations using the MATHPRINT interface?

Yes, our online TI-84 emulator supports MathPrint formatting for fractions, exponents, roots, logs, summations, and integrals.

12. Can the TI 84 online be used for calculus operations (derivatives & integrals)?

Yes. The calculator supports:

• Numerical derivative (nderiv)

• Numerical integral (fnInt)

These tools work under the MATH menu and operate just like the physical one.

13. Can I use this TI-84 online calculator for SAT, ACT, AP exams, or other standardized tests?

No. Online calculators are usually not permitted during official exams. You can use it for studying, practicing menus, learning TI-84 navigation before the exam, and completing homework efficiently.

14. Does the TI-84 online calculator support storing and graphing lists from the STAT menu?

Yes. You can enter data into L1, L2, L3, etc., and generate scatter plots, histograms, box plots, and regression equations. All list-based graphing tools are available in our tool.

15. Can I reset the entire calculator if it freezes or I want to clear everything?

Most online TI-84 tools include a “reset” or “reload” option. If something becomes unresponsive, simply refresh the browser tab. The calculator reloads instantly with default settings.
