' - - File: XVIa Solve Boundary Value Problem (BVP) 
'   An example of a nonlinear BVP with multiple roots.
'   The derivatives X'(..} shown  as a1 & a2 were found from File XVIbRoots.

' Given: X"(t) - 1.5 X{t}^2 = 0

F{t,x,y} = y
G{t,x,y} = 1.5 x^2

to = 0: xo = 4: tb = 1: xb =1 : n = 100 : a1 = -35.9:  a2 = 3
