Hello. When I solved problem I found that my solution is different from one in textbook. I am wondering if I am doing anything wrong or if sample solution is wrong. Task: Prove equality by using definition. My solution. 1)We have to show that 2)Let . Implications are valid\ 3)(provided that so ). By taking ,we get Sample solution 1)We have to show that 2)Let . Implications are valid\ 3)(provided that so ). By taking ,we get Only difference is that sample solition has  where I have + and + where I have . Is there any reason why sample solution should have  instead of + or is it just they're typo?
