Zero | The Solve aplet found a point where |
| the value of the equation (or the root |
| of the expression) is zero within the |
| calculator’s |
Sign Reversal | Solve found two points where the |
| value of the equation has opposite |
| signs, but it cannot find a point in |
| between where the value is zero. |
| This might be because either the two |
| points are neighbours (they differ by |
| one in the twelfth digit), or the |
| equation is not |
| the two points. Solve returns the |
| point where the value is closer to |
| zero. If the value of the equation is |
| a continuous real function, this point |
| is Solve’s best approximation of an |
| actual root. |
Extremum | Solve found a point where the value |
| of the equation approximates a |
| local minimum (for positive values) |
| or maximum (for negative values). |
| This point may or may not be a root. |
