Differential Equations problem

Click For Summary
SUMMARY

The discussion centers on solving the differential equation (x - y ln(y) + y ln(x))dx + x(ln(y) - ln(x))dy = 0. The user initially struggled with various methods including exactness, separation of variables, and homogeneity. Ultimately, the user identified the equation as homogeneous and noted that factoring out a -y from the first term clarified the solution process. This highlights the importance of recognizing the type of differential equation for effective problem-solving.

The Attempt at a Solution



I have attempted for exactness, have attempted at separating the variables, checked if it was homogeneous, and thrown every method I know at this problem. I am usually excellent with DE, I am at a loss with this problem.

Nevermind, it's homogenous. After you factor out a -y from the first term it becomes more obvious.

Thanks anyway!
