The graphing calculator provides a UI similar to a real 84 graphing calculator.

◉ Graphing Calculator

- Supports function, polar, and parametric graphs.

- Press MODE and select Graph mode, then press Y= to open the graph editor. Press GRAPH to draw the functions.

- Interactive and manual tracing modes.

- Shows intersections, roots, and extrema (local maxima and minima) of function graphs.

- Shows derivatives of function graphs.

- Shows tangents to function and polar graphs.

- Best‑fit line for a set of points.

- TABLE generates a table of values for the selected graph.

- CALC computes min, max, d/dx, and integrals of the selected graph.

◉ Scientific Calculator

- Includes a computer algebra system for symbolic calculation.

- Supports all functions of real 83 and 84 graphing calculators.

- All basic and advanced math functions: complex numbers, probability, angles, relational operations, logic operations, and matrix and vector operations.

- Users can define custom calculator functions.

◉ Equation Solver (press ALPHA ENTER to open the SOLVER menu)

- Solves any equation with Auto Solver mode and can provide symbolic roots.

- Solves quadratic, cubic, quartic, and quintic equations.

- Solves systems of equations with up to 5 variables.

◉ Statistics

- 1‑Var Stats: calculates 1‑variable statistics.

- 2‑Var Stats: calculates 2‑variable statistics.

- LinReg(ax+b): fits a linear model to data.

- QuadReg: fits a quadratic model to data.

- CubicReg: fits a cubic model to data.

- QuartReg: fits a quartic model to data.

- LinReg(a+bx): fits a linear model to data.

- LnReg: fits a logarithmic model to data.

- ExpReg: fits an exponential model to data.

◉ Inferential Statistics and Distributions
