$\displaystyle y''+\frac{1}{x}y'+(1-\frac{a^2}{x^2})y=0$

y1(1)=3 y2(1)=-8.1

y1(1)=3 y2'(1)=5.4

i need to deside:

A.

y1 and y2 are lenear dependant on (0,+infinity)

B.

y1 and y2 are not lenear dependant on (0,+infinity)

C.

we cant know if y1 and y2 are dependant only by a single point

i don tknow how to solve this equation

in a similar question i was told to use y=x^a

but here its not working

i am no get a certain a for which the equation is zero
