Math Graphix Lab Pro

: Interactive 2D/3D function grapher for learning and teaching.
2D: Built-in functions (linear, polynomial, trig, exponential, etc.), custom expressions, live f(x) at any x, adjustable parameters.
Calculus: Derivative f'(x), integral ∫f(x), Compare mode, Trail.
Live Random: Random x exploration with adjustable speed and trail.
Learning: Info panel (formula, description, domain, range, properties), reset view, save graph as PNG.
3D: Surface plots z = f(x,y), rotate/zoom, animation and trail...
