The figure doesn't show the direction of rotation

### What specific section or headline is this issue about?

Syntax

### What information was incorrect, unhelpful, or incomplete?

The function `rotate(angle)` rotates (presumably) "in clockwise direction".
However, the angle shown in the diagram has arrows in both directions.
[Also the angle is suddenly called `alpha` instead of `angle`.]

However, since the coordinate system uses a flipped y-axis,
it is no longer obvious which way "in clockwise direction" is.

The explanation and diagram needs to match.
One way of getting rid of "clockwise" is to talk about rotating the x-axis towards the y-axis
in the direction where the rotation is least.

### What did you expect to see?

An angle indication with only one arrow.

### Do you have any supporting links, references, or citations?

Wikiepedia has a pate on "angular displacement".

https://en.wikipedia.org/wiki/Angular_displacement

Note that they are using a standard, righthanded coordinate system,
so their "clockwise" doesn't match yours "clockwise".

### Do you have anything more you want to share?

_No response_
