yeKciM THANKYOU but are you 100% positive this is correct answer,,,i just want like one other peron to confirm it. i fully understand now that my original thinking is correct due to the diagram drawn above everything makes sense i think,,,,although still trying to do the other question i found
btw i lost my password y day,,,,,,,,,,,,,,,,,,,,created new account,,,,ive confused myslef again,,i cant believe it,,why did we choose to put dydx and then do the dx integral first i thought you cant do that? is the reason we put dy first because x>y?????
furthermore by doing the x integral first do we not have to change the limits in which case it doesnt work youd get x from y to infinity and y from 0 to infinty thanks?
]i.e you cannot do dx first when dy came fist
