`dy/dx = 3x^2/y^2` Find the general solution of the differential equation

`(dy)/dx = 3x^2/y^2`


This differential equation is separable since it can be rewritten in the form


`N(y)dy = M(x) dx`


So separating the variables, the equation becomes


`y^2dy = 3x^2dx`


Taking the integral of both sides, the equation becomes


`int y^2dy = int3x^2dx`


`y^3/3 + C_1 = 3*x^3/3 + C_2`


`y^3/3 + C_1 = x^3 + C_2`


Since C1 and C2 represent any number, it can be expressed as a single constant C.


`y^3/3 = x^3 + C`



Therefore, the general solution of the given `y^3/3 = x^3 + C` .
