- TL;DR Summary
- I have a data set where the y values oscillate like a trig function, but not exactly.

I have a table of values (from my own analysis, not from a textbook) that represents a portion of a periodic function:

What function satisfies the table? What I know is that the function is periodic. I was thinking I could use cosine because its maximum is at x=0.

x | y |

0 | 30 |

1 | 20 |

2 | 10 |

3 | 10 |

4 | 20 |

5 | 30 |
