Hi, I wonder why wronskian must be constant.(adsbygoogle = window.adsbygoogle || []).push({});

I know that p(x)W[u1(x),u2(x)]=constant, according to the Abel's theorem, but

wouldnt there a special case that W[u1(x),u2(x)]=c/p(x).

Then for this special case, W[u1(x),u2(x)]=/=c and satisfies Abel's theorem.

Is it ok to ignore this special case?
