OPEN LAB
Experiments
Small interactive math labs for trying ideas quickly. Pick an experiment, move the sliders, and watch the graph answer back.
Quadratic Graph
Change a, b, and c in y = ax^2 + bx + c to see the parabola, vertex, roots, and direction.
Linear Graph
Adjust slope and intercept in y = mx + b to see how a line tilts, crosses the axes, and moves.
