graph sin x from 0 to pi/2
on the same graph plot cos x from 0 to pi/4
Note that cos x from pi/4 to pi/2 is identical to sin x from pi/4 to pi/2 with only a reflection.
Thus for every value of ln sin x from pi/4 to p/2 there is an equal value of ln cos x from 0 to pi/4. Therefore the areas under will be identical.
Damon: That is a good answer which now I really understand.I thank you very much.
