Detailed method of drawing Fibonacci sequence on geometric sketchpad

The problem of drawing the Fibonacci sequence on the geometric sketchpad that has troubled you for a long time, finally has a detailed solution! PHP editor Strawberry will bring you the solution to this problem, come and find out quickly!

1. Select [Data]-[New Parameter] f1=0, f2=1, select [Data]-[Calculation] f1 f2, right-click to select the calculation result, select [Properties]-[ Tag] changed to f3. Continue to create a new parameter a1=1, calculate a1 1, a1 1 1, and create a new parameter n=30.

2. Select f1, f2, a1, n in sequence, press the Shift key, and select [Transform] - [Depth Iteration]. a1? ——a1 1, f1——f2, f2——f3, click [Iterate].

3. Right-click the table, select [Draw Data in Table], in the pop-up dialog box, click x in the [Select Point] item, and set the x column to (a1 1) 1, column y is f3.

4. As can be seen from the image, the number sequence grows very slowly at the beginning, but it is very amazing at the end.

Analysis: 1. The prerequisite of the sequence is a1=1, a2=1, because an=an-1 an-2, so the original image is a1, a2, and the initial image is a2,a3.

2. Because f3=2 when iterating 0 times, the subscript should be 3, and a1=1, so calculate a1 1 1.
