A visual pixel-counting approach to definite integrals — graph a function, measure the signed area, and see exactly why the number is right.
The full 15-slide deck, including six real PixelFuture runs checked side-by-side against Wolfram|Alpha — including a case with no elementary closed form. Nothing here is a mockup.
Every number below came from an actual PixelFuture run compared against a known exact value — not a marketing estimate.
