"Area"
 
  
The area below the sine function from 0 to Pi/2 is 1 an exact number so I thought it could have an elementary demonstration(not using calculus). I would love a simple geometric proof, perhaps thinking on the harmonic movement could give some clue?

   Dear Friend,
I think that it is impossible, because we cannot transform this curved-side triangle (line y=0; line x=pi/2; f(x)=sin(x))
to a normal triangle (normal, I mean, a triangle that we can measure its area)
We can't even find (by a ruler & a compass) the place of pi/2
