calculate start angle and end angle of arc
Use the derivatives of the equations that parameterize the arc.
Dear George,
I refer you to the following link which contains an example:

Hoping this will be helpful,

Hello George, could you provide us with a schema?
I can't figure out if differential calculus is necessary, or if trigonometry is sufficient.
Gabriel
It depends on how your arc is defined (approximately by sequence of coordinates, explicitly by parametrization, implicitly by equations), and in what space (R2, R3, ...)
I agree with you Sjoerd, we have not enogh information to give a satisfactory answer. What is an arc in this context?
