Best ResponseYou've already chosen the best response.4or the other way around seems like if you are able to find one, you should be able to find the other it is not like one is more difficult or something

Best ResponseYou've already chosen the best response.4yeah they are both \(\frac{\sqrt 2}{2}\)
