Graphing Calculator

This tool provides a browser-based calculator designed for quick numeric computation, function evaluation, and basic data operations. It supports a range of modes including scientific, graphing, and statistics to match practical math workflows.

Conceptually, input expressions are parsed by an infix-to-postfix engine, which applies operator precedence and function lookup to produce accurate results. Graphing mode samples a function over a domain and renders a visual plot, while matrices and vectors are handled via dedicated algebra routines.

Benefits include students who study algebra and calculus, engineers performing quick checks, and analysts who need lightweight tools without installing software. The tool emphasizes correctness, predictable formatting, and locale-aware number handling to support diverse learners.

Core features include arithmetic, exponents, trigonometric and inverse functions, logarithms, statistics, matrix operations, and complex numbers. Optional capabilities such as graphing, unit handling, and history enhance productivity without compromising the core calculation workflow.
