I teach at a high school and should like to find out, if I can use R for my
teaching. So I jhave installed it on my XP system and now I should like to
solve a simple problem:
We have just measured dx and dt (d standing here for \Delta) on an inclined
plain and received some data thet are in two lists (x_list and t_list). The
theory says, that dx = a/2*(dt)^2 for a constant a.
I should like to fit the data against the theoretical prediction. This
should deliver an estimate for a.
Then I should like to graph the data (as bullets) and the predicted
function into the same graph.
Is this possible? I suspect that the answer is "yes" and that R is an
overkill for this.
Could somebody tell me how to do these things? (I need only a few lines of
MuPad or Maple for this; the problem is that I own a MuPad license but the
school does not.)
