Let ä(t) satisfy the differential equation x"(t) + 14tx (t) = 0 for all t > 0.
On the interval t > 0, define the functions x₁(t) = x(t) and x₂(t) = x"(t). Use the differential equation to express
x₂ (t) in terms of x(t). Note: Enter x (t) as x.
Answer: x₂(t)
Enter the smallest pair of non-zero, integer values of A and B that satisfy the equation Ax₁ (t) + Bx₂(t) = 0 if any.
If there are no non-zero values enter 0 for each.
Answer: A
=
=
3
B =
Therefore, for t > 0, the two functions must be:
A. The same.
B. The answers to the Navier-Stokes existence and smoothness problem.
C. Linearly independent.
D. Linearly dependent.
E. Undefined.
F. Discontinuous.
