Somebody really loved Pythagoras, and
compiled 370 proofs or somesuch.
But then made a bold claim that no
trigonometric proofs are possible.

Fact or fiction?
Ok, ChatGPT got smarter:
Apply the angle sum/difference identity for cosine:
cos(A - B) = cos(A) * cos(B) + sin(A) * sin(B)
Substitute A = B into the equation:
cos(0) = cos^2(B) + sin^2(B)
Simplify further:
1 = cos^2(B) + sin^2(B)
Does this count?
