I will try this one more time. First of all, I do NOT believe bees can do calculus. That is kind of my whole point. Second, your comparison would work if you presented it like this:
You tell me that you are going to throw a ball to me. You tell me the starting height, the angle, the force, wind speed, etc. Then you ask me to place my hand where I think the ball will be so I can catch it but you add the requirement that once I position my hand, I can't move it. If I knew calculus, I could calculate the position fairly accurately and place my hand in the right spot to catch the ball.
That is, essentially, what we are asking the bees to do. We know, a priori, what the displacement has to be in order to minimize surface area (i.e. bee's wax) when constructing the pointy end of the honeycomb. (That's like the placement of the hand in the throwing example.) Then the bees start building and, low and behold, the displacement they build in to the pointy end matches the value we came up with that minimizes the wax used. And, no, bees can't do calculus. That's the WHOLE POINT.
So what exactly is your point? When the behavior of bees and termites and birds building nests has been carefully investigated the rules for their construction behavior turn out to be very simple and involve no knowledge or calculations.
