Determine order and degree (if defined) of differential equations given in \[\mathbf{y’’’}\text{ }+\text{ }{{\left( \mathbf{y’} \right)}^{\mathbf{2}}}~+\text{ }\mathbf{2y}\text{ }=\text{ }\mathbf{0}\]
Determine order and degree (if defined) of differential equations given in \[\mathbf{y’’’}\text{ }+\text{ }{{\left( \mathbf{y’} \right)}^{\mathbf{2}}}~+\text{ }\mathbf{2y}\text{ }=\text{ }\mathbf{0}\]

The highest order derivative present in the differential equation is  and its order is 2.

The given differential equation is a polynomial equation in derivatives  and  and the highest power raised to highest order  is one, so its degree is 1.

Hence, order is 2 and degree is 1.
