When SOLVE Cannot Find a Root
Sometimes SOLVE fails to find a root. The following conditions cause the message
:
The search terminates near a local minimum or maximum (see figure a,
below). If the ending value of
f(x)
(stored in the Z–register) is relatively close
to zero, it is possible that a root has been found; the number stored in the
unknown variable might be a 12–digit number very close to a theoretical
root.
The search halts because SOLVE is working on a horizontal asymptote—an
area where
f(x)
is essentially constant for a wide range of
x
(see figure b,
below). The ending value of
f(x)
is the value of the potential asymptote.
The search is concentrated in a local "flat" region of the function (see figure c,
below). The ending value of
f(x)
is the value of the function in this region.
