MCQ
The general solution of the differential equation $\frac{{dy}}{{dx}} = \frac{{{x^2}}}{{{y^2}}}$ is
  • ${x^3} - {y^3} = c$
  • B
    ${x^3} + {y^3} = c$
  • C
    ${x^2} + {y^2} = c$
  • D
    ${x^2} - {y^2} = c$

Answer

Correct option: A.
${x^3} - {y^3} = c$
a
(a) We have ${y^2}dy = {x^2}dx$

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