Connecting points to make a curve
Answered
Hi. I have been trying to make a graph of a airfoil for a project work. I initially inserted all the points accordingly now I have to make a line pass through the points. I tried 'fit' but it doesn't work and I don't know why. So can you please help me? I don't know whats the wrong here.

such a wave form makes me think that the command FitSin[<LIst of Points>] is appropriate, one for the upper part and one for the lowerpart. I made a small example and didn't copy exactly all the points of the screenview.
Once you get the expression for f(x) you can limit the domain with the command Function[ f, <Start xValue>, <End xValue> ]

please add the file

sin() has a simetry that your points does not have
I think better you can use Spline[] or see this topic
