I've been trying to extract elements from a list x={a,b,c,d,e...}
then square each value and pair it up with the original unsquared value.
These two values form a point (2Dim) and I then try to pair up each
point with a given vertex of {5,25} and use Line[{{5,25},{a,a^2}}] to
graph this thing.
My main routine (reAlly kinda small)
is...Do[n=x[[i]];Line[{{5,25},{n,n^2}}],{i,10,1}]
When this is run nothing happens....
in this case x={5,5.5,5.4,5.3,5.2...ect}
I've been stuck for 2 weeks unable to get this to work and it is driving
me
crazy because it should be sooo easy.
