Find the order and degree (if defined) of the following differential equations. `((d^2y)/(dx^2))^2 + cos ((dy)/(dx)) = 0`

Text Solution

Verified by Experts

The highest order derivative in the differential equation is `(d^2y)/(dx^2)` . `therefore` The order of the differential equation = 2. The degree of the differential equation is not defined.
