Hi, I am currently trying to draw a standard airfoil NACA 4412 (http://en.wikipedia.org/wiki/NACA_airfoil). I've put all the equations and defined the parameters.

I don't know what is the problem, probably many Float undefined errors... According to me, it should be simple, but somehow I can't get it right. Any suggestions?

Thanks
