Differential Equations - Intervals of Validity

3/6/2018, · First note that if y o = 0 y o = 0 then y ( t) = 0 y ( t) = 0 is the solution and this has an interval of validity of. − ∞ < t < ∞ − ∞ < t < ∞. So, for the rest of the problem let's assume that y 0 ≠ 0 y 0 ≠ 0. Now, the differential equation is separable so let's solve it and get a general solution.
