a. Verify that both y1(t) = 1 − t and y2(t) = −(t^2)/4 are solutions of the initial value problem y' = ((−t )+ ((t^2) +4y)^(1/2))/2 , y(2) = − 1 Where are these solutions valid? b. Explain why the existence of two solutions of the given problem does not contradict the uniqueness part of the existence and uniqueness for non-linear equations theorem.
Added by Mark W.
Step 1
Substitute y1(t) = 1 - t into the differential equation: y' = ((-t) + (t^2 + 4(1 - t))^(1/2))/2 y' = ((-t) + (t^2 + 4 - 4t)^(1/2))/2 y' = ((-t) + (t^2 - 4t + 4)^(1/2))/2 y' = ((-t) + (t - 2)^2)^(1/2))/2 y' = ((-t + t - 2))/2 y' = -1 Now, substitute y(2) = -1 Show more…

1. A. State the conditions of the theorem guaranteeing a unique solution to the nonlinear initial value problem y?=f(y, t), y(to) =yo. B. Check the conditions of the theorem for the initial value problem y?=(?t+?(t^(2)+ 4y))/(2), y(2) =?1. C. Verify that y1(t) = 1?t and y2(t) =?t^(2)/4 both are two solutions of the above problem. Does this contradict the theorem you stated in a)? Why?

Consider the equation (*) ay'' + by' + c = 0, where a, b, and c are constants. Let y1 and y2 be the linearly independent solutions of (*). Prove that (y1(x))^2 + (y2(x))^2 ≠ 0 for all x ∈ R.
