NumWorks Online Emulator

NumWorks' free browser emulator provides screenshot, full-screen and session controls for demonstrations and remote learning. In the linked version 21 manual, Grapher accepts functions, inequalities, points and curves: add an expression, then view its graph or value table. Plot restrictions limit the drawn domain, while axis bounds and zoom change the viewing window. Tables have start, end and step settings and an exact-results option. The Find controls cover roots, intersections and bounded integrals; the manual specifically requires the point to be in the current window for finding x from y. Session controls are visible on the emulator page, but their storage lifetime is unspecified. Examination permission depends on the examination's rules.
