# another area under the curve qn

I was wondering! Who told you it was wrong? Another of those "computer" systems where you have to give the answer in exactly the right form? I hate those things! $-ln(\sqrt{2}/2)$ is perfectly correct but can be simplified. $-ln(\sqrt{2}/2)= ln(2/\sqrt{2})= ln(\sqrt{2})= ln(2)/2$. Try one of those forms.
