![**Problem Statement:**
Find a linear differential operator that annihilates the given function. (Use \(D\) for the differential operator.)
\[ 2 + e^x \cos 4x \]
**Explanation:**
You are asked to determine a differential operator using \(D\) (where \(D\) represents differentiation with respect to \(x\)) that, when applied to the function \(2 + e^x \cos 4x\), results in zero.
The function is composed of:
1. A constant term \(2\).
2. A composite function \(e^x \cos 4x\), which involves an exponential function and a trigonometric function.
The process involves finding an operator that accounts for the characteristics of these components, particularly focusing on differential operations that involve exponential and trigonometric terms.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F25fce74d-50ce-4010-8593-c528dce466b9%2F6047554f-af73-49a4-a7a9-0eadbb53d77e%2F4pkgt1o_processed.png&w=3840&q=75)
