General solution of a differential equation (separable)

Click For Summary
SUMMARY

The general solution of the differential equation y' = 4t - ty² is derived through separation of variables. The discussion confirms that the approach taken is correct, emphasizing the importance of knowing the subset of R for y. If the range is unspecified, it is advisable to retain the modulus in the solution without further specification. This ensures the solution remains valid across the entire domain.

PREREQUISITES
  • Understanding of differential equations, specifically separable equations.
  • Familiarity with the concept of separation of variables.
  • Knowledge of the modulus function and its implications in mathematical solutions.
  • Basic calculus skills, including differentiation and integration techniques.
NEXT STEPS
  • Study the method of separation of variables in differential equations.
  • Learn about the implications of specifying ranges for solutions in differential equations.
  • Explore the use of modulus in mathematical functions and its significance in solutions.
  • Investigate additional examples of separable differential equations to reinforce understanding.
USEFUL FOR

Students studying differential equations, mathematics educators, and anyone seeking to deepen their understanding of separable differential equations and their solutions.

Homework Equations


y'=4t-ty^2


The Attempt at a Solution


I 'think' this question is pretty straight forward but I'm still not sure if I did it right or not. I have two question. One till the last step that I have done, have I done it correctly 2. How do I proceed from there? The attempt is attached.

What you've written is correct. Normally, you should know on what subset of R you're looking for y. If not, then keep the modulus there and don't explicitate.

The proff didn't give any range for y. So by don't explicitate you mean I should keep it the way it is?
