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).
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 search is concentrated in a local "flat" region of the function (see figure c,
below).
In these cases, the values in the stack will be same as the values before executing
SOLVE.
Checksum and length.
Cancels Equation mode.
