यदि ` y= log (1+cos x ),` सिद्ध कीजिये की `(d^(3)y)/(dx^(3))+ (d^(2)y)/(dx^(2))*(dy)/(dx)=0 `

y=log(1+cos x), prove that (d^(3)y)/(dx^(3))+(d^(2)y)/(dx^(2))*(dy)/(dx)=0

If y=log(1+cos x), prove that (d^(3)y)/(dx^(3))+(d^(2)y)/(dx^(2))(dy)/(dx)=0

If y=log(1+sinx)," then "(d^(3)y)/(dx^(3))+(d^(2)y)/(dx^(2))(dy)/(dx)=

" 2"(d^3y)/(dx^(3))+(d^2y)/(dx^(2))-(dy)/(dx)-y=0 find degree and order.

If y="log"(1+cosx),"p r o v et h a t"(d^3y)/(dx^3)+(d^2y)/(dx^2)dot(dy)/(dx)=0.

If y=log(1+cosx) , prove that (d^3y)/(dx^3)+(d^2y)/(dx^2)dot(dy)/(dx)=0 .

If y=log (log 2x) ,then x ( d^(2)y)/(dx^(2))+(dy)/(dx) =

If x=log pandy=(1)/(p), then (a) (d^(2)y)/(dx^(2))-2p=0 (b) (d^(2)y)/(dx^(2))+y=0 (c) (d^(2)y)/(dx^(2))+(dy)/(dx)=0( d) (d^(2)y)/(dx^(2))-(dy)/(dx)=0

If y=cos (log x) ,then " "x^(2) (d^(2)y)/(dx^(2))+x(dy)/(dx)=
