Question
**Problem Statement:**

Find the particular solution to the differential equation:

\[ y'' + 6y' + 9y = e^{-3t} \arctan t \]

**Solution:**

\[ y_p(t) = \text{(Your Solution Here)} \]

**Explanation:**

This problem involves finding a particular solution to a second-order linear non-homogeneous differential equation. The left side of the equation is a linear combination of the function \(y\) and its derivatives, while the right side is the non-homogeneous part, which in this case is the product of \(e^{-3t}\) and the arctangent function of \(t\).

The solution process typically involves using methods such as undetermined coefficients or variation of parameters to find a particular solution. After finding the particular solution, it can be added to the complementary (homogeneous) solution to find the general solution to the differential equation.
