Apples and oranges multiplied by qumkwats equals Kiwis. Do a little research instead of asking us to do it for you. Why would you want to calculate that? In the real world all that data is available from charts and graphs and tables for any sweptwing aircraft out there. And MAC is really only necessary for sweptwing aircraft. Straight wings just use chord line.I'd almost swear I read you can find the MAC from the aspect ratio: If so what's the formula to determine this?

I was thinking of practicing some art and making some drawings that have at least some accuracy in themDo a little research instead of asking us to do it for you. Why would you want to calculate that?
It's the calculus symbol for an integral. Conceptually it's kind of like imagining a wing, let's say, chopped into an infinite number of cordwise slices then taking whatever value you wanted to measure (lift maybe?) for each slice, added them all up, and thus derived your desired value for the entire airfoil. Simple, huh? You've just been treated to all I understand about integral calculus. Any more questions, ask one of the numerous engineers on this forum.

This useful? What's that long f like thing?

Zipper, if you dismiss calculus you are living in the world of the Pilgrim Fathers, before Newton and Leibniz. Unless you understand that f thing and that calculus thing you cannot understand what any equation with a square or cubic function in it actually means or does. Having stated that you don't understand it and have no intention of learning anything about it I cant understand why you keep asking questions, unless endlessly asking questions is an end in itself.Basics and Symbols: Feel free to correct me as I suck at math, though largely written so I can just go to this page and cut & paste.
- ∫ = Integral, some calculus thing that has to do with x's and y's that I have no real grasp of...
- dx, or dy = related to integrals, d being an infinitely small slice of x, or y, whatever that be...
No, I wasn't... I just wanted to have the symbology available and a sort of glossary readily available on a forum I'm on so often.Zipper, if you dismiss calculus you are living in the world of the Pilgrim Fathers, before Newton and Leibniz.
I never took calculus... just to be clear, I don't object to learning. From what it looks like the upper and lower numbers seem to be related to coordinates...Unless you understand that f thing and that calculus thing you cannot understand what any equation with a square or cubic function in it actually means or does.
Your reply clearly showed you had not opened and read the link I posted. Differentiating a squared equation gives its gradient, when that gradient is zero it is at a limit which yields useful information. Any straight line on a graph has a gradient "m" it will normally cross a square function curve at two points, the area between the line and the curve also reveals important information, while the point on the curve with the same gradient as the line (a tangent) reveals other important information as does the difference between that line and any line parallel to it.No, I wasn't...

So the integral is a gradient so if the top is 1 and the bottom is zero it's a gradient of 0 to 1 or 1 to 0? Do you always work in 1/5's? Or others? I'm looking at the wiki-pageYour reply clearly showed you had not opened and read the link I posted.
Zipper you must have been a straight A student and much loved by your teacher. I clearly stated "differentiate" in the link you will read that integration and differentiation are opposites, but both equally useful.So the integral is a gradient so if the top is 1 and the bottom is zero it's a gradient of 0 to 1 or 1 to 0?

Depends on the subject...Zipper you must have been a straight A student and much loved by your teacher.
Sorry about thatI clearly stated "differentiate" in the link you will read that integration and differentiation are opposites, but both equally useful.
Zipper, you spend plenty of time on this forum, so by now you should have formed some opinions about who is knowledgeable about the quantitative aspects of aircraft performance and who is not. Go to their profile pages and see if they identify themselves as engineers.Who should I contact?
