only reversed, gotta have the constant last or you won't get a constant as an answer!

but order doesn't matter if you have constants

If 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.
