36 interactive simulators for graphs, probability, sampling, linear algebra, filters, circuits, and component behavior.
This page is a cross-category simulator directory. Each simulator still belongs to its subject area, while this index helps users quickly find visual tools for math, statistics, matrix transformations, and electronics circuits.
Visualize function graphs, transformations, growth models, waves, Fourier series, and Taylor approximations.
Explore unit circle angles, coordinates, sine, cosine, tangent, and periodic behavior.
Simulate distributions, sampling, regression, confidence intervals, hypothesis tests, and Monte Carlo experiments.
Visualize 2D linear transformations, eigenvectors, dominant eigenvalues, and iterative matrix behavior.
Simulate circuits, filters, diode curves, resonance, time constants, voltage dividers, and control response.
Simulator pages are not a separate subject competing with math, statistics, or electronics. They are visual tools collected from those categories. Keeping each simulator in its original subject path helps the site structure stay clear while giving users one place to browse interactive pages.
Free online calculators and tools covering mathematics, unit conversion, text processing, and daily life. Accurate, fast, mobile-friendly, and completely free to use.
