  3. In the Definition section of the dialog box, enter a value for each input or output parameter of the function:

    • x0: Value of the independent x quantity at the approximative start of the step.
    • F (x0): Value of the dependent F(x) step height at the start of the step.
    • x1: Value of the independent x quantity at the approximative end of the step.
    • F (x1): Value of the dependent F(x) step height at the end of the step.
