Summary
| Description |
English: Visualisation of the complex roots of y = ax² + bx + c where a is positive and the discriminant, b² - 4ac is negative, by CMG Lee. The parabola is rotated 180° about its vertex (yellow). Its roots are rotated 90° around their mid-point, and the plane is interpreted as the complex plane (green). The example shown has a = 1, b = -2 and c = 5. |
