In CATIA, how is the function of "fog" defined?

Let's take the sine function as an example.

Define formulas using custom variables and related functions (note the consistency of units, otherwise an error message dialog box will appear).

The sine function is shown in the figure.

If both x and y are real numbers, then it can be expressed as **y = a * sin(b * x * 360deg)**, where **a** is the amplitude and **b** is the number of cycles.

1. First, establish the FOG function.
