You almost lost me there, but I'll forgive the slip ....this time.
Trying to translate your meaning...
You have two points at the extremes (0,40) and (50,70).
The times for the points you need are 1 second apart. Now the fun begins:
You MUST know the nature of the curve in order to find the points between.
Otherwise there is an infinite number of solutions. If it is linear [a line]
then the interval between 40 and 70, being 40(70) will be 110. That must
also be divided equally into 50 parts. So each part will measure 110/50 =
2.2.
Pairs [points] will then be (0,40), (1,37.8), (2,35.6), (3,33.4), .... and so on
to (50, 70).
However, if not linear, you must say what the relation is that determines the
interval, for it will then not be equal intervals.
You can do this on a spreadsheet if you have trouble ...being a programmer, that
should not be difficult.
