Evaluate `int_-1^ 1 sin^5xcos^4xdx`

Explanation

To evaluate the integral \( \int_{-1}^{1} \sin^5 x \cos^4 x \, dx \), we will analyze the function to determine if it is odd or even.

### Step 1: Identify the function
Let \( f(x) = \sin^5 x \cos^4 x \).

### Step 2: Check if the function is odd or even
To determine if \( f(x) \) is odd or even, we need to evaluate \( f(-x) \):
\[
