For each of the differential equations given below, indicate its order and degree(if defined).
(i) `(d^(2)y)/(dx^(2))+ 5x((dy)/(dx))^(2) - 6y = log x`
(ii)`((dy)/(dx))^(3) - 4((dy)/(dx))^(2) + 7y = sin x`
(iii)`(d^(4)y)/(dx^(4)) - sin ((d^(3)y)/(dx^(3)) = 0`

Answer

(i) Order 2; Degree 1
(ii) Order 1; Degree 3
(iii) Order 4; Degree not defined
