Question

What is the order of the differential equation \[\frac{dy}{dx} - \cos x = 0\]?

Options

• Order = 1

• Order = 0

• Order = 2

• Order = 3

Answer 1

The order of a differential equation is determined by the highest order derivative appearing in the equation. In this equation, the highest order derivative is \[\frac{dy}{dx}\], which is a first-order derivative. Therefore, the order is 1.
