True Output

Does anyone know how to do truth tables?

Can anyone figure out how to make truth tables for the following questions and if the following symbolized statements are tautologous, self-contradictory, or contingent? 1. N horseshoe (N horseshoe N) 2. (G horseshoe G) horseshoe G 3. (~K horseshoe H) triple bar ~(H v K)

1. 1: N<(N<N) T T T F F F this is a tautology, which basically means it is obviously true. If N is true, then N is true. See? 2: (G<G)<G T T T F F F This is also a tautology. Its essentially the same as above. 3: (~K<H)=~(HvK) T T T T T(T)F F FTT Therefore this is self-contradictory
