On my DE test, I was asked to determine if two solutions to a DE are fundamental solutions.(adsbygoogle = window.adsbygoogle || []).push({});

So I confirmed they were both solutions, and took the Wronskian, which was nonzero.

I got points marked off, and he put a minus sign in front of my wronskian result.

Isn't the sign of the Wronskian determined by what function I call y1 and what function I call y2 and is thus completely arbitrary?
