Inspectable methods
Every lab states its method and limitations instead of presenting a black-box answer.
RESEARCH & SIMULATION LABS
Advanced calculation workspaces that keep the method visible.
Use focused labs for symbolic algebra, numerical differential equations, linear programming, DC circuit analysis, and statistical inference. Each workspace makes scope and assumptions clear.AVAILABLE LABS
Choose a method before choosing more controls.
Each workspace is separate so the main result, assumptions, and next step stay easy to find on desktop and mobile.dy/dxOpen →∂Open →maxOpen →ΩOpen →tOpen →
Differential Equations Lab
Model first-order ODEs and two-state systems with controlled initial conditions, step sizes, solution curves, phase plots, and numerical tables.
First-order ODEs: y′ = f(x, y) · Two-state systems: y′ and z′ · Euler, Improved Euler (Heun), and RK4Symbolic Algebra Lab
Simplify and differentiate expressions, evaluate a model at a chosen value, or compare two forms with a clearly labeled algebra-engine result.
Symbolic simplification · Symbolic derivative · Numeric evaluationOptimization Lab
Build a two-variable linear program, inspect feasible corner points, and calculate a maximum or minimum objective value in a transparent browser workspace.
Up to eight linear constraints · Maximize or minimize objective · Optional non-negative constraintsDC Circuit Analysis Lab
Use transparent ideal-circuit calculations for resistors, voltage division, RC transients, and a two-node nodal-analysis model.
Ohm's law and power · Series and parallel resistors · Voltage dividerAdvanced Statistics Lab
Use an inference-focused statistics workspace for t-tests, correlation, simple regression, and one-way ANOVA with visible assumptions.
Two-sided p values · Confidence interval for a sample mean · Welch unequal-variance t-testFocused workspaces
Research tasks need dedicated inputs, results, tables, and charts rather than a crowded one-size-fits-all calculator.
Connected analysis
Move naturally between graphing, matrices, statistics, units, and numerical models when a problem needs more than one view.
