Find the general solution of the differential equation `(dy)/(dx)-y=cosx`

Explanation

To find the general solution of the differential equation \(\frac{dy}{dx} - y = \cos x\), we will follow these steps:

### Step 1: Identify the standard form
The given differential equation can be rewritten in the standard linear form:
\[ \frac{dy}{dx} + p(x)y = q(x) \]
Here, we have:
