Sir or Madam,
I have a set of (x,y)points (seven to be exact).
Using ListPlot I get roughly a
polynomial-type parabola. (ax^2 + bx + c).
They are :launch angle vs. distance; given
a launch speed and an unknown lift.
Now on the TI85 graphing calculator, I heard
one can get the thing to guess or approximate
an equation for a given set of points.
I know Mathmatica can do this. But the
directions seemed geared to a person with
a MUCH more extensive math background. In
short, I cannot follow them.
So please give me a short laymen's version
of doing this kind of thing.
Thanx In Advance,
