A Differential Equation. NEED your help

  1. Jun 27, 2010 #1
    Hi everyone, I need your help. I am getting trouble in two differential Equation.

    The first one:
    How can I solve the family of Differential Equation y' = -y*(y-6)^2 - a ? I want to sketch the bifurcation diagram, and what value can “a” be? THX.

    The second one:
    A DE y' = (1/t)*(2*y + 1). Does there exist a unique solution that satisfies y(-1) = 0? If so, find it. If not, find all solutions and explain why this does not contradict the uniqueness Theorem. How to solve it? Plz.
    I am now waiting the answers online. Thx.

    What have you tried? Per the rules of this forum, you need to show some effort at the solution of homework problems.

    The second one, i think, there is only one solution.

    Moderator's note: thread moved to Homework forums from Differential Equations.
    If you don't explain how you figured that out, people could assume you are just doing a random guess, which really isn't making an attempt at solving the problem.
