List of all members.

Detailed Description

A Tangent line is a line that is tangent to the graph of a specified function of one argument at a specified value of its argument. If added to a CoordinateRect, it will appear as a line. A TangentLine is a Computable object, so should be added to a Controller to be recomputed when the Value or Function changes.
