Scientific Calculator

This tool provides a multi-field scientific calculator that supports a broad range of mathematical operations and functions. It mirrors TI-like capabilities conceptually by offering a consistent evaluator, multiple input fields, and advanced features on demand. Users can perform arithmetic, trigonometry, logarithms, exponentiation, roots, and factorials, while optional modules enable matrix operations and statistics for more complex analysis. The underlying architecture parses each input, applies operator precedence, and computes results with robust error handling. Conceptually, the tool separates input collection from computation, allowing users to compare results side by side across expressions or datasets. It benefits students performing homework, engineers validating designs, and researchers exploring data transformations, all within a single, repeatable workflow. Unique value lies in the combination of multi-field inputs and optional advanced math features, which reduces the need to switch tools mid-work and improves reproducibility across related calculations. Core features include an expression evaluator, function support (sin, cos, tan, log, sqrt, exp, factorial), constants (pi, e), and optional matrix and statistics capabilities. Use cases span classroom exercises, quick engineering checks, and data analysis tasks that require consistent numeric results without graphical output or scripting. The tool emphasizes reliability, precise numeric formatting, and clear error signaling for domain issues such as invalid inputs or math-domain violations.
