Hi I am trying to figure out how to caculate a cosine graph for the following data points:

X Y

0 5.2

2.3 33.9

4.16 55.7

6.48 13

8.80 12.8

10.98 58.4

12.34 52.4

14.48 11.00

16.61 16.00

18.46 55.2

20.42 57.8

22.57 10.2

I need to find the Beginning point, the end point, the period, B, the phase shift, C, D, and A! Any help would be greatly appreciated

The following might be of some use. The results were obtained using a non-linear fitting routine (part of a technical software package) - not the sort of thing you want to do by hand!:
