Just take any example of the given question and prove that the statement is true.

Give a Lazy Fitch style proof outline of a sentence. For example, you should be able to give a Lazy Fitch style proof outline of the following sentence: Va3b: (Q(a) = (P(a,b) V P(b, a))). Let a be arbitrary. Construct b somehow, possibly dependent on a. Assume Q(a) is true Use that P(a,b) V P(b, a) is equivalent to -P(a,b) = P(b, a). Assume -P(a,b) Show the P(b, a) is true under all of these assumptions Cujp v Grani) 2 Ta (5P)-> ( 3x: (Aw 1 800) (10 () kx ( (A, E, Bai) = (ty (P VG Ta ks ] ( Acson Bw E) p) 1 (Vn A (n)) => [up rq (3) poolth (Ack) n BCki)) 3D [->3)] => [ 3x (Acx, xv r)] wers (49 [3x (Acx= Bay)] v [ Vx ( Buy)] (46 (P vg) Acrah) Athena 3 4
