Encouraged by the success of Exact Solution of Uda Equation (2) @ Quantum History Theory @ Products, I began to hope that any classical motion appears asymptotically generally as a delta function factor in a solution.
In this page, I try to write such a solution for harmonic oscillator problem.
x(t) = A sin(ωt - B),
x(a) = A sin(ωa - B),
x(b) = A sin(ωb - B).
ωa - B = sin-1[x(a)/A], ωb - B = sin-1[x(b)/A],
ω(b - a) = sin-1[x(b)/A] - sin-1[x(a)/A],
sin[ω(b - a)] = [x(b)/A]cos{sin-1[x(a)/A]} - cos{sin-1[x(b)/A]}[x(a)/A]
= ±[x(b)/A]√{1 - [x(a)/A]2} ± [x(a)/A]√{1 - [x(b)/A]2}
= ±[ [x(b)/A]√{1 - [x(a)/A]2} + [x(a)/A]√{1 - [x(b)/A]2} ]
or ±[ [x(b)/A]√{1 - [x(a)/A]2} - [x(a)/A]√{1 - [x(b)/A]2} ]
A2sin[ω(b - a)]
= ±{x(b)√[A2 - x(a)2] + x(a)√[A2 - x(b)2]}
or ±{x(b)√[A2 - x(a)2] - x(a)√[A2 - x(b)2]}.
How about putting as follows?
Φ[χ] = δ( lima→-∞limb→+∞{χ(b)√[A2 - χ(a)2] + χ(a)√[A2 - χ(b)2] - A2sin[ω(b - a)]} )F[χ].
For the present, I decided to stop going on this way more because of too less hope.(2019/10/14)
