4.7.1.2.10 Sine Spiral Transition Segment

The sine spiral transition segment is a special case of a spiral where the curvature rate of change is a sine function and the terms are dependent on the length L measured from the inflection point. The parameter value is defined as the deflection i.e. bearing angle &Theta.

The values of its individual terms are identical and equal to the length of the segment L: SineTerm = L LinearTerm = L

The following diagram shows the generic classes and relationships used when applying this concept.
