In the Nov. 1981 Course 110 Exam Problem No. 34

Why couldn't we use the limits for x as 0<x<1/2??

I somehow got the right answer for the joint density but didn't use the limits of 1/2y to 1/2 for x. I used 0<x<1/2!! When i compared my result. I knew it was wrong but couldn't figure what else to do.

Dr. Krzys could you kindly help me out...thanks!
