ODE for nth order can be written as; F(x,y,y’,….,y n) = 0. Separation of the variable is done when the differential equation can be written in the form of dy/dx = f(y)g(x) where f is the function of y only and g is the function of x only. In examples above (1.2), (1.3) are of rst order; (1.4), (1.5), (1.6) and (1.8) are of second order; (1.7) is of third order.
