Best ResponseYou've already chosen the best response.1but order doesn't matter if you have constants

Best ResponseYou've already chosen the best response.1If both bounds are constants then often not, but sometimes the integral is only possible in a certain order. In this case we have the bounds as one constant, and one function. You could have done this one in the other order, but you would have to change the inner function to terms of yu.
