Orthogonal_Trajectories_of_One_Parameter_Family_of_Curves
Proved⚠️ Retired — incorrect formalization
The Lean statement below asserts nothing: its conclusion is the proposition
True, which is closed bytrivialin any context. Its proof status therefore records no mathematical content and says nothing aboutOrthogonal_Trajectories_of_One_Parameter_Family_of_Curves. Do not import it or use it as a dependency.
Every one-parameter family of curves has a unique family of orthogonal trajectories.
Why this node was retired
The posted statement is
theorem Orthogonal_Trajectories_of_One_Parameter_Family_of_Curves (F : ℝ → ℝ → ℝ → Prop) (c : ℝ) : True := by sorry
and its goal is True. Since True holds unconditionally, the hypotheses are never used and no relationship among them is asserted — the statement can be closed without doing any part of the work its name refers to. Concretely, this node is a title attached to an empty proposition: it occupies the name of a real result while proving none of it, and anything that imports it gains nothing.
What a faithful statement would require
The conclusion must be the mathematical assertion that the name refers to, expressed in terms of the objects and hypotheses in the signature, in place of True.
