Differential Equations Question 37

Question: The general solution of the differential equation $ \frac{dy}{dx}=\frac{x^{2}}{y^{2}} $ is

Options:

A) $ x^{3}-y^{3}=c $

B) $ x^{3}+y^{3}=c $

C) $ x^{2}+y^{2}=c $

D) $ x^{2}-y^{2}=c $

Show Answer

Answer:

Correct Answer: A

Solution:

We have $ y^{2}dy=x^{2}dx $

Integrating, we get $ y^{3}-x^{3}=c $

Therefore $ x^{3}-y^{3}=c $ .
