variable to see the best estimate
ISOLVEI
has found so far. To restart the
search from where it left off, display the best estimate (it becomes your
initial guess) and solve the equation again.
If the value stored in the unknown leads you to believe that

is not
proceeding towards a reasonable answer, you can enter new guesses and
solve again.
