SUMMARY

The discussion focuses on solving the differential equation given by y(1+xy)dx + x(1-xy)dy = 0. Participants explored various methods including the variable separable method, substitution with u=xy, and v=x/y, but found these approaches ineffective. The use of an integrating factor, specifically 1/(xy)^2, was suggested as a potential solution strategy. Ultimately, the consensus is that traditional methods may not suffice for this equation, necessitating alternative techniques.

Ok so I tried to solve the following differential equation for y by every method (variable separable method/making to variable separable method technique/putting y/x=other variable/making homogeneous to solve equation to get y/x ).But I think I can't solve this particular equation by these methods.

y(1+xy)dx + x(1-xy)dy =0
