1. The problem statement, all variables and given/known data Find the general solution of Solve yux - xuy = xyu2 Next, solve the Cauchy problem with the Cauchy data x = y = u 2. Relevant equations 3. The attempt at a solution My teacher told us we should investigate how to solve this. The problem is we just have seen linear first order PDE, but this is non-linear! Could you please give me a hint or a name to start with?
