I have just learnt the first order system of ODE,(adsbygoogle = window.adsbygoogle || []).push({});

i found that the Wronskian in second order ODE is |y1 y2 ; y1' y2'|

but in first order system of ODE is the Wronskian is W(two solution),

i wonder which ones is the general form?

thank you very much
