Description

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
