Problem 1.3 c
w(t)^2
= w(t1) + y(t1)x(t1)^2 < this is from the PLA iteration <=(w(t1) + y(t1)x(t1))^2 < a property: a + b <= a + b = w(t1)^2 + 2y(t1)w(t1)x(t1) + y(t1)^2x(t1)^2 = w(t1)^2 + 2y(t1)w(t1)x(t1) + x(t1)^2 Now, it seems like 2y(t1)w(t1)x(t1) is somehow <= 0. w(t1)x(t1) is >= 0 tho. hence, it seems like 2y(t1) is somehow <= 0. It seems like I am on the wrong track as I am not using the hint mentioned in the question at all. Any pointer? Thanks! 
Re: Problem 1.3 c
This inequality a + b <= a + b is quite loose in general and you may want to consider not using it. Hope this helps.
