Best ResponseYou've already chosen the best response.0Isn't \[\int\limits \frac{x4}{x^3}dx=\int\limits \frac{y^23}{y^4}dy\] enough?

Best ResponseYou've already chosen the best response.0Anyway: don't ask me HOW to integrate that (use Wolfram integrator if you just want the answer), it's probably some counterintuitive trig substitution.

Best ResponseYou've already chosen the best response.0i got \[ \frac{ 1 }{ x } + \frac{ 2 }{ x^{2} }\frac{ 1 }{ y } + \frac{ 1 }{ y^{3} } = C\] am i right?

Best ResponseYou've already chosen the best response.0@gerryliyana in this type of differntial eqution, we use separation of variable technique as we can see from this differential equation, variables can be separated easily
