' - - File: XVIbr2  Find second root.
'   An example of a nonlinear BVP with multiple roots.
'  Find the roots by setting the "switch" at the far right to zero and using a1,a1 framing.

' 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 = -10  :  a2 = -5

BVP[F, G, {to,xo,tb,xb} { a1, a2 } {1, .001, 0}]   ' <--  set to zero for each of two trials.
