When Quadratics Leave the Real Line: An AI Complex-Root Explorer

Expired

Complex Quadratic Root Explorer develops Complex roots of quadratic equations through six visual, misconception-first stages.

The discriminant, exact algebra and Argand locations are linked in one progression. Non-real roots become interpretable points with symmetry and magnitude, so the quadratic formula is not an isolated manipulation.

From Coordinates to Polar Meaning: An AI Argand Observatory

Expired

Argand Modulus and Argument Observatory develops Representation of complex numbers in the Argand diagram, finding the modulus and argument of a complex number through six visual, misconception-first stages.

Modulus and argument are learned as measurable geometric quantities attached to a point, not as disconnected formulas. Dragging, radius and angle cues coordinate Cartesian and polar descriptions while preserving exact values.
