SUMMARY

The discussion centers on a miscalculation in applying the Bernoulli Method to a differential equation. The error occurred when transitioning from the first line to the second line, specifically in the division by 3(1+x^2). The correct formulation should be dy/dx + (2xy)/(3(1+x^2)) = (2xy^4)/(3(1+x^2)). This correction is crucial for obtaining the correct solution.

PREREQUISITES
  • Understanding of the Bernoulli Method in differential equations
  • Familiarity with algebraic manipulation of equations
  • Knowledge of differential calculus
  • Ability to interpret and solve first-order differential equations
NEXT STEPS

When I plug what I get for y back into the original Eq. to check it, it doesn't pass. I did something wrong somewhere but it all seems right to me. Where did I go wrong?

You made a mistake in going from the first line to the second: you divided by ##3(1+x^2)## but did not distribute the division to the ##2xy^4## term. Your second line should look like

$$\frac{dy}{dx} +\frac{2xy}{3(1+x^2)} = \frac{2xy^4}{3(1+x^2)}.$$

Try your calculation again and see if it works out.
