3RR warning 

Three times today (28 Oct.) you have reverted the "sinusoids" language to your preferred "trigonometric functions" language, as I've tried various things to explain, reference, talk about it, etc.  Please engage rather than just reverting.  If you revert again, I'll report you for 3RR violation again.  

Neither you nor I are experts in the article subject matter (least squares spectral analysis). But I cited 2 references that literally say "trigonometric functions", while your references all refer to another method (Fourier analysis) you freely interpret as to make it sound they refer to the article subject matter, though it is obvious they do not (in your mind, as you claimed it explicitly, Fourier analysis is still the same as least-squares spectral analysis, which is obviously a nonsense because WP has two completely separate articles both featured on WP main page btw).  So I do not believe anyone any more will buy your misusing of Wikipedia regulations. There is no reversals here, not even technically speaking; because what is going on is mine (article author’s) cleaning of all the shit you keep spraying around. Just like so many editors noted (everyone just look at Dicklyon’s talk page) that you engaged in edit wars or insults exchanges with so far. You are just a trouble maker around here and everyone sees you as such. Now stuff your imaginative misinterpretations of WP regulations to where they belong.  No 3RR violation on my part. But I know why you just threatened with reporting me: it is because I already mentioned to you today that you are in violation of 3RR yourself. "Sinusoids" is another result of your imagination as NO REFERENCE ON LSSA EVER MENTIONS IT, so it is not a reversal to remove your ignorance, cleaning your shit is what it is.
