1) Let P={(a,b,c):a,b,c ∈ Z(integer), and a^2+b^2 = c^2}, and T = {(p,q,r): p = x^2-y^2
, q =2xy, and r=x^2+y^2, where x,y ∈ Z(integer)}. Show that T is a subset of P.
2)⇒, ∨, ∧, and ⇔ are logical operations we have studied briefly. How many different logical operations can there be?
Thank you so much!
