About Graphing Calculator 84: Calc84
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 the functions you use on 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
- Z‑Test, T‑Test, 2‑SampZTest, 2‑SampTTest, 1‑PropZTest, 2‑PropZTest, Z‑Interval, T‑Interval, 2‑SampZInt, 2‑SampTInt, 1‑PropZInt, 2‑PropZInt, Chi‑square Test, Chi‑square GOF Test, 2‑SampFTest, LinRegTTest, LinRegTInt, ANOVA.
- All distribution functions, including Normal, Student’s t, Chi‑square, F, binomial, and more.
