Plot/calculate values of equation

Hi.

I was wondering if it is possible for Excel 2007 to calculate values for an equation without resorting to the usual way
of creating a list of step values and inserting the formula in each cell.
Example:

What I would like to do is to have a cell where I can type the number of steps and the size of step increments
I want to calculate and then plot the resulting curve in a chart.
The way I described above is fine for smaller lists, but I want to calculate 30000-40000 steps sometimes.

Thanks in advance for any help.


Best regards
