# Analyze FunctionUse this dialog box to set up parameters of the function analysis. You can enter the formula of a function or select it in the **"Y(x)="** combo box. This combo box contains list of formulas of functions of Y(x) type, whose graphs exist in the active document. Select the **Zeroes of Function** and/or **Extrema** check box if you want to find zeroes/extrema of the function. You can select the interval over which the function will be analyzed by the **Minimum of X** and **Maximum of X** edits. The entered values are actual and they are not related to the coefficients of X (see Plot Options). If you select the **Use Derivative** check box, the analytically determined derivative will be used to find the extrema of the function. **Note**: it is not always possible to find zeroes and extrema with the accuracy specified in the **Accuracy (Decimal Signs)** edit. |
