If `y=x^(4)`, find `(d^(2)y)/(dx^(2))and(d^(3)y)/(dx^(3))`.

If y=e^(4x) sin 3x , find (d^(2)y)/(dx^(2)).

y=x^(3)-4x^(2)+5 . Find (dy)/(dx) , (d^(2) y)/(dx^(2)) and (d^(3)y)/(dx^(3)) .

If m, n are the order and degree of the differential equation ((d^(4)y)/(dx^(4)) + (d^(2)y)/(dx^(2)))^(3//2) = a (d^(3) y)/(dx^(3)) respectively, then 2m + n=

If (d^2y)/(dx^(2))=xe^x then (d^(3)y)/(dx^(3)) =.....

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

Order and degree of the differential equation ((d^(2)y)/(dx^(2)))^(5)+ (4 ((d^(2)y)/(dx^(2)))^(3))/((d^(3)y)/(dx^(3))) + (d^(3)y)/(dx^(3)) = x^(2) - 1 respectively are

(x^(2)d^(2)y)/(dx^(2))=(x(dy)/(dx)-y)^(3) Find Degree.

What is the degree of the differential equation. ((d^(4)y)/(dx^(4)))^(3//5) -5 (d^(3)y)/(dx^(3)) +6(d^(2)y)/(dx^(2))-8 (dy)/(dx)+5=0 ?

IF y^3=x^2+y^2 , find (d^2y)/(dx^2) at y=1.
