Pregunta: x * y ^ 3 * d/dx (y) = y ^ 4 - x ^ 4; y(1) = 2

We have given differential equation is $\mathrm{x}\times {\mathrm{y}}^3\times \frac{\mathrm{d}\mathrm{y}}{\mathrm{d}\mathrm{x}}=({\mathrm{y}}^4-{\mathrm{x}}^4)$ , and $\mathrm{y}\left(1\right)=2$ here we can use the variable seprable method of diffe...
