SUMMARY
The discussion focuses on finding orthogonal trajectories for the family of curves defined by the equation (x-c)² + y² = c². The initial approach involves deriving the first derivative, resulting in y' = -(x-c)/y, and subsequently substituting c with (x² + y²) / 2x. The transformation leads to y' = 2xy / (x² - y²). However, it is established that this is not a separable differential equation but a homogeneous equation, allowing the substitution of v = y/x to convert it into a separable form.
