Re: area between curves

If the intention is to include all area for |x| < 3, we would add to [color=#00BF00]skipjack[/color]'s area with (and using the same symmetry of an even function taken over an interval symmetric about the functions' axis of symmetry.):



Thus, the total area A would be:

I was adding the result [color=#00BF00]skipjack[/color] obtained in the post above the one you are referring to.
