Statement

forall (u : Vec), forall (v : Vec), forall (P : Prop), forall (mk : forall (forward : forall (h : Perp u v), @Eq.{1} RingElem (dot u v) zero), forall (backward : forall (h : @Eq.{1} RingElem (dot u v) zero), Perp u v), P), P

Proof term

fun u => fun v => fun P => fun mk => mk (fun (h : Perp u v) => h) (fun (h : @Eq.{1} RingElem (dot u v) zero) => h)
