If `y = a cos (log x) - b sin (log x), then x^2y_2 + xy_1 + y =`

Find the second order derivative of the following functions If y = a cos (log x) + b sin (log x), prove that x^2y_2 + xy_1 + y = 0 .

If y = a cos (log x) -b sin (log x), thenx ^ (2) y_ (2) + xy_ (1) + y =

If y =a cos (log x) + b sin (log x) then x ^(2) y _(2) + xy _(1)+y=

If y = 3 cos (log x) + 4 sin (log x) show that x^2 y_2 + xy_1 + y = 0
