WebbWhat you have proved, in effect, is this: if the desired identity holds, then sin ( sin − 1 x) = x holds. But that doesn't prove that your identity holds. After all, if − 1 = π holds, then sin ( sin − 1 x) = x holds, but we're certainly not going to claim that − 1 = π anytime soon!

Webb25 mars 2024 · The original equation, $~x^4-4x^3-14x^2-4x+1=0, ~$ is a symmetrical quartic equation. This means that the coefficients of the $~x^4~$ and $~x^0~$ terms are equal and that the absolute value of the coefficients of the $~x^3~$ and $~x^1~$ terms are equal..
