Periodic Solution to Differential Equation

  1. Sep 10, 2014 #1
    For each epsilon greater than 0, show that the differential equation x'=x^2-1-cos(t)-epsilon has at least one periodic solution with 0 less than x(t) less than or equal to (2+epsilon)^1/2

    Seriously review the homework submission guidelines for this forum. As with my answer, your question needs to show a bit more to be helpful.
