Question
Determine order and degree (if defined) of differential equations given in Exercise.
$\frac{\text{d}^2\text{y}}{\text{dx}^2} =\text{cos} 3\text{x}+\text{sin} 3\text{x}$

Answer

The given differential equation is
$\frac{\text{d}^2\text{y}}{\text{dx}^2} =\text{cos} 3\text{x}+\text{sin} 3\text{x}$
The highest order derivative present in the given differential equation is $\frac{\text{d}^2\text{y}}{\text{dx}^2}$ and index of its highest power is 1.
$\therefore$ the given differential equation is of order is 2 and degree 1.
