24.6.7  Tangents to curves in the plane

See Section 25.5.3 for tangents in space.

The tangent command finds tangents to curves.

Examples

C:=circle(0,1,color=blue); T:=tangent(C,3+2i,color=orange)
purge(t):; t:=element(0..pi,pi/3):; C:=circle(0,1,color=blue); A:=element(C,t); T:=tangent(A,color=orange)

When tangent is called with an element, the tangent will change along with the point on the element.
