EqCalc vs Linear Algebra Visualizer

EqCalc‑G is an educational and engineering reference tool for calculating gaseous chemical equilibrium using Gibbs free‑energy minimization. Designed for students, researchers, and practicing engineers, the app provides a fast, portable way to explore equilibrium behavior in hydrogen and hydrocarbon systems under ideal‑gas assumptions. Key Features: • Includes a publicly available thermochemical dataset derived from NASA curve‑fits of the NIST‑JANAF tables for selected species • Import your own thermochemical datasets in Aerotherm, Chemkin, or NASA CEA formats • Flexible reactant specification:
 - Define mixtures on a mole or mass basis - Or specify fuel mixture, air, and fuel‑air equivalence ratio • Export results easily by copying output to the clipboard for use in your favorite notes or spreadsheet apps Basic vs. Plus Version: The free Basic version supports fixed enthalpy and pressure equilibrium calculations.
Upgrade to Plus version to unlock additional problem types: • Fixed temperature & pressure • Fixed entropy & pressure • Fixed internal energy & volume • Fixed temperature & volume • Fixed entropy & volume NASA/NIST Notice: Use of NASA and NIST thermochemical data does not imply endorsement, certification, recommendation, or approval of this app, its developer, or any results produced.

Ever wondered what a matrix is really doing? Whether you're learning it yourself or teaching students who are stuck, this app lets you visualize and manipulate matrix transformations, so you can finally see how and why they work. WHY IT CLICKS Most apps show you the answer. This one shows you why. The columns of a matrix are just where the basis vectors î and ĵ land. Column one is red. Column two is green. Follow those colors from your input, through the transformed vectors, into the step-by-step math. One number, traced all the way to its effect. With Linear Algebra Visualizer you: - Can finally build the visual intuition of linear algebra - Understand the math behind each transformation - Visually see why TRS order matters - Understand the effect of adding multiple matrices and translations - Watch eigenvectors and eigenvalues come alive BUILT FOR - Students surviving their first linear algebra course - Graphics programmers who want intuition, not just formulas - Teachers who need a live demo that lands - Anyone who's stared at a matrix and thought "but why does this work?" - Visual thinkers who've struggled to picture it all in their head Stop memorizing matrices. Start seeing them. Download Linear Algebra Visualiser: Rotate, Scale, Shear, Reflect, Translate and learn to understand transformations visually.
