### Description

A computational design approach to sagiita.

The sagitta is the height of an arc.

It is the perpendicular from the midpoint of the arc’s chord to the arc itself.

First step is to define the circle and the equation in a code block

Second step is to project the point determined by sagitta height on the circle.

Now that we have the arc determined, we can chose to move it to the center point of the circle. That way we can easier control any derivation geometry

Finally a custom node may look like this:
