Symmetric Let x;y 2R Suppose that x ˘y Since x ˘y we have that x2 = y2 So y 2= x Therefore y ˘x Transitive Let x;y;z 2R Suppose that x ˘y and y ˘z Since x ˘y we have that x2 = y2 Since y ˘z we have that y2 = z2 So x 2= y = z2 Therefore x ˘z (c)Draw a number line Draw a picture of the equivalence class of 1 Repeat this for. Problem4(WR Ch 3 #11) Suppose an ¨0, sn ˘a1 ¯¢¢¢¯an, and P an diverges (a) Prove that P a n 1¯an diverges Solution Assume (by way of contradiction) that P a n 1¯an converges Then an 1¯an!0 by Theorem 323 Since an 6˘0, we can divide the top and bottom of this fraction by an to get 1 1 an ¯1!.
