Transcribed Image Text:This information can be summarized as follows:
If p²-4q> 0, the characteristic equation has two distinct, real
roots A and A₂. A fundamental set of solutions is
₁ (t) = e^it and y(t) = et
If p² - 4q = 0, the characteristic equation has one repeated real
root λ. A fundamental set of solutions is
y₁ (t) = et and y2(t) = te^t.
• If p²-4q<0, the characteristic equation has two complex con-
jugate roots a tib. A fundamental set of solutions is
yi(t) = el cos bt and y2(t) = et sin bt.
.
In Exercises 25-36, find the solution of the given initial value
problem.
