(choose chapter or problem)

(a) Prove that if x, y, z is a primitive Pythagorean triple in which x and z are consecutivepositive integers, thenx = 2t(t + 1) y = 2t + 1 z = 2t(t + 1) + 1for some t > 0.[Hint: The equation 1 = z - x = s2 + t2 - 2st implies thats - t = l.](b) Prove that if x, y, z is a primitive Pythagorean triple in which the difference z - y = 2,thenx = 2t y = t2 - 1 z = t2 + 1for some t > 1.
