We know that:
Theorem (*) If y₁, y₂ are linearly dependent on some interval, and their derivatives y'₁
and y', exist on that interval, then W[y₁, y₂] =0, there if W[y₁, y₂] =0, then: y₁, y₂ are
linearly dependent on that interval? That is, the converse theorem of theorem(*)
would be true.
Study this situation in the following cases:
Y₁ (x)=x² Y₂ (x)=X|X|,
functions defined at -1<x<1, then:
Find the Wronskian of y1 and y2.
Show that the functions are not linearly dependent on:
-1<x<1
