Sorry if this is a dumb question, but how do I turn a table into an equation? I need the line or curve to fit the points. And I need the line or curve to periodically go back to zero in between each point. Below are my numbers and straight line slopes.

__x y Slope__

1 20

2 8 -12

3 9 1

4 19 10

5 27 8

6 9 -18

7 19 10

8 27 8

9 1 -26

10 27 26

11 20 -7

12 5 -15

13 19 14

14 20 1

Questions:

1) Since I want the equation to periodically return to zero in between each point, is there a way that I can model this as a sin or cos wave (or a combination)? That would make sense, right?

2) Or if I want straight lines, how do I do that without having 14 piece-wise functions?

3) Also, is there a way maybe to find the pattern of the slopes and make dY/dX equal to that pattern? That way I can work backwards using some calculus?

Thanks
