DarkWiz Lab · study tools that react
Every lesson here is a working instrument, not a page of notes. Move a value and the figure, the formula and the full solution rebuild in front of you — so you see why the answer changes, not just that it did.

sin²θ + cos²θ = 1.000 Quadrant I
On the bench
Every DarkWiz Lab app is a single self-contained page that runs on its own subdomain. Math is finished and open. The others are being built with the same engine.
81 topics from place value to integral calculus. Rotatable 3D figures, worked solutions that show every substitution, and scored quizzes drawn from a pool of thousands of questions.
Kinematics, forces, energy, waves and circuits — with vectors you can drag, free-body diagrams that resolve themselves, and graphs that redraw as the motion changes.
Stoichiometry, gas laws, solutions and equilibrium. Balance an equation and watch the mole ratios, the limiting reagent and the yield follow it through.
Distributions you can reshape, samples you can re-roll, and confidence intervals that widen and narrow as you change n. Ideas that only make sense once you can move them.
Inside the math app
Ordered so each topic leans on the one before it — the same path a course takes, from arithmetic through to integral calculus.
How a lesson runs
The loop is the same whether you are dividing fractions or finding a volume of revolution, so there is nothing to relearn when the mathematics gets harder.
Choose a subject, then a branch, then a topic. Each one opens with a plain definition and a note on where the idea is actually used.
Every measurement is a control. Change a radius, an angle, a coefficient — the figure redraws the instant you let go of the slider.
Each formula appears three ways: the general rule, your numbers substituted into it, and the result — with the reasoning underneath, in sentences.
Quiz yourself on one topic or a whole branch. Answers feed mastery bars and streaks, so you can see which topics still need another pass.
