Tangent to curve through outside point
Since it is part of the math program in the Netherlands I want to demonstrate that also tangents to curves exists through an outside point. (Not on the curve)
The Tangent command seems to allow this straightforward since it asks for a point and a curve. But it does not result in the real tangents.
I do not succeed in finding a general approach. :( For example, in the attached file, not all tangents are found when the point is moved.
Is there a general approach possible? :confused:
