Graphing math
TI-84 Plus-style graphing calculator
Graph functions, trace points, build a value table and calculate with a familiar TI-84 Plus-style keypad.
How to use this calculator & common questions
Solve a common problem
Open Solve a problem / examples for guided quadratics, linear equations, two-equation systems, mean and standard deviation, derivatives or definite integrals. Enter the labeled values and choose Solve & save answer. History, comparisons and exports retain that task and its answer.
Graph a function
Press Y= and enter a function using x, such as x^2 - 4 or sin(x). Use * when multiplication must be explicit. Press GRAPH to draw it. WINDOW opens editable Xmin, Xmax, Ymin and Ymax values; ZOOM restores the standard −10 to 10 view.
Trace and table
TRACE moves across the graph and reports the current Y₁ value. STAT opens a five-row value table across the selected window. MODE switches between degrees and radians for trigonometry. Press ENTER to save a result to history.
Based on the familiar TI-84 workflow
The compact key order follows the supplied TI-84 Plus button reference and this TI-84 tutorial video. Texas Instruments documents graphing, tables, zoom tools, numeric analysis and scientific functions on its official TI-84 Plus product page.
This is an independent web calculator, not TI firmware or a ROM emulator. It focuses on numeric arithmetic and single-variable function graphing, so some handheld applications, statistics, programming, matrix and exam-mode features are not reproduced.
