# Мы убедились, что в граничных случаях ( {1},{2},{3} ) треугольник решения КУ вырождается.
Домашнее задание: исследовать КУ с корнями (0.01; 4), (-0.01; 4), (1.99; 2.01)
= Интересно. Мы с тобой рассуждаем о КУ уже 6 дней. Создается впечатление, что такие разговоры можно вести бесконечно.
— Согласен.
