You can use dsolve for boundary value problems you just have to give the
boundary conditions as the ICs argument e.g.:
In [*27*]: f = Function('f')
In [*28*]: t = Symbol('t')
In [*29*]: dsolve(f(t).diff(t, 2)-f(t))
Out[*29*]:
-t t
f(t) = C₁⋅ℯ + C₂⋅ℯ
In [*30*]: dsolve(f(t).diff(t, 2)-f(t), ics={f(0):0, f(1):0})
Out[*30*]: f(t) = 0
In [*31*]: dsolve(f(t).diff(t, 2)-f(t), ics={f(0):0, f(1):1})
Out[*31*]:
t -t
ℯ ℯ
f(t) = ───────── - ─────────
2⋅sinh(1) 2⋅sinh(1)
