I am not a mathematician but have an interest in maths which doesn't actually go as far as actually doing calculations! I discovered this "fact" by playing with a calculator. I was unable to work out how to differentiate the function which is what you need to do no doubt to show what its maximum is.Can anyone give me some insight as to why this fact is a fact? The one who gets the 10 points will have to explain it in a very simple clear way suitable for someone whose knowledge of analysis is very elementary indeed.
