Question

If `p a n d q` are the order and degree of the differential equation `y(dy)/(dx)+x^3( d^2y)/(dx^2)+x y=cos x , t h e n` `p q` d. none of these
A. p lt q
B. p = q
C. p gt q
D. none of these

Answer 1

Correct Answer - C
The given differential equation is of order 2 and degree 1.
`therefore" p = 2 and q = 1 "rArr p gt q`
