Full-featured graphing engine with equation plotting (Y=), numerical derivatives (nDeriv), definite integrals (fnInt), matrices, and statistical regressions.
Runs directly in web browsers on Mac, Windows, Google Chromebooks, iPads, and mobile devices. No APKs, browser extensions, or Java installations needed.
The Online TI 84 Calculator reproduces authentic Texas Instruments TI-84 Plus CE graphing workflows for high school and college coursework. Master these essential features:
Press the [Y=] button in the top row. Enter your function (e.g. Y1 = X^2 - 4 using the [X,T,θ,n] variable key). Press [GRAPH] to render the curve. To find zeros or intersections, press [2nd] + [TRACE] (CALC) and select Intersect (5) or Zero (2).
Press [MATH]. Select option 8: nDeriv( to compute numerical derivatives at a specific point d/dx(f(x)) at x = a. For definite integrals, select 9: fnInt( to compute definite integrals from a to b with MathPrint notation.
Press [2nd] + [x⁻¹] (MATRIX). Navigate to EDIT, define dimensions for Matrix [A], and enter coefficients. Return to the matrix menu under MATH and choose rref( (Reduced Row Echelon Form) to solve systems instantly.
Press [STAT] > 1: Edit to populate list data into L1 and L2. Then press [STAT] > CALC to execute LinReg(ax+b), QuadReg, or 1-Var Stats.
Switch between models at any time using the selector at the top of the page:
Best for Algebra I & II, Geometry, Trigonometry, Pre-Calculus, AP Calculus AB/BC, AP Statistics, Physics, and College Engineering.
Ideal for Middle School, General Science, Chemistry, Biology, SAT without calculator section practice, and standardized exams prohibiting graphing calculators.
