WebSep 29, 2024 · One approach is tried was to find the values of (x,y) where f (x,y) and g (x,y) simultaneously change their sign and feeding those as the initial conditions. This approach works reasonably well until you supply equations which don't change sign after a zero crossing. (For example f (x,y) = x^2)
