Vector Algebra

Question

Determine order and degree (if defined) of differential equations:
y″ + 2y′ + sin y = 0





Answer

The given differential equation is
y'' + 2 y' + sin y = 0
The highest order derivative present in the given differential equation, is y' and the index of its highest power is 1.
∴ the given differential equation is of order 2 and degree 1.
