Answer» Correct Answer - a The given differential equation can be rewritten as ` y + (d^(2)y)/(dx^(2)) = [ x + ((dy)/dx)^(3//2) ]^(2)` ` rArr y + (d^(2)y)/(dx^(2)) = x^(2)+ ((dy)/dx)^(3) + 2x ((dy)/dx)^(3//2)` ` rArr [ y + (d^(2)y)/(dx^(2)) - x^(2) - ((dy)/(dx))^(3)]^(2) = [ 2x ((dy)/dx)^(3//2) ]^(2) = [ 4x ((dy)/dx)^(3)]` ` :. ` Order and degree of the given differential equation and 2 respectively . |
