Prizm FX-CG50 Color Graphing Calculator

Prizm FX-CG50 Color Graphing Calculator

A full-featured color graphing calculator modeled after the Prizm FX-CG50. This web-based calculator provides high-resolution 2D and 3D graphing, comprehensive scientific functions, statistics with regression analysis, and matrix operations. All computation is performed entirely in your browser.

Features

• Run Mode: Full scientific calculator with trig, log, exponential, powers, roots, factorial, complex expressions, DEG/RAD/GRAD modes, and ENG notation
• 2D Graphing: Plot up to 4 color-coded functions simultaneously, zoom, pan, trace mode with coordinate readout, and adjustable window settings
• 3D Surface Plots: Wireframe 3D surface visualization with rotation controls for z=f(x,y) expressions
• Conic Sections: Graph circles, ellipses, parabolas, and hyperbolas with adjustable parameters
• Table of Values: Generate value tables for all defined functions with configurable range and step
• Statistics: 1-variable and 2-variable statistics, histogram and scatter plot visualization, linear/quadratic/exponential/power/logarithmic regression with R-squared
• Normal Distribution: PDF and CDF calculations with custom mean and standard deviation
• Matrix Operations: Multiplication, determinant, inverse, transpose, and row-reduced echelon form (RREF)

How to Use

1. Use the Run tab for scientific calculations. Type expressions and press EXE to evaluate.
2. Switch to Graph to enter up to 4 functions (Y1-Y4). Use soft keys for zoom, trace, window settings, 3D, and conic modes.
3. Use the Table tab to see computed values for your graph functions over a specified range.
4. The Statistics tab provides data analysis with regression fitting and distribution calculations.
5. Press SHIFT (yellow) or ALPHA (red) for secondary and alphabetic key functions.
