B Happy Christmas: Is it Really True?

Click For Summary
The discussion centers on the validity of a mathematical claim related to the binomial theorem and its resemblance to Chebyshev polynomials. Participants question the truth of the assertion and its implications. The effectiveness of Chebyshev polynomials is noted, particularly their utility for cosines, while their application to sines is deemed less beneficial. The conversation also hints at potential rule violations due to repeated postings. Overall, the thread explores the intersection of mathematical concepts and their practical applications.

Is this really true? It resembles the binomial theorem.
I've posted it twice which might be breaking rules. Happy Christmas PF.
