Warning on Order of Differential Equation
Consider the ordinary differential equation:
- $y'' - y'' + y' - y = 0$
At first glance it looks as though it is of the $2$nd order.
But after some (fairly obvious) simplification, it is seen that it can be written:
- $y' - y = 0$
which is of the $1$st order.
