In mathematics<span>, </span>trigonometric identities<span> are equalities that involve </span>trigonometric functions<span> and are true for every value of the occurring </span>variables<span> where both sides of the equality are defined. Geometrically, these are </span>identities<span> involving certain functions of one or more </span>angles<span>. </span> So we know this identity:
There appears to be a very loose negative correlation between the data.
The screenshot is attached of the graph. The data does not form a very tight line, so it is not a strong correlation, but it does appear to generally decrease.
