The integral in the image is:

\[
\int \cos(x) e^{\sin(x)} \, dx
\]

We are given \( u = \sin(x) \), which suggests using a substitution approach to simplify the integral.

### Solution:

1. **Substitute \( u = \sin(x) \):**
   - Then, \( \frac{du}{dx} = \cos(x) \), or \( du = \cos(x) \, dx \).

2. **Rewrite the integral in terms of \( u \):**
   - The integral now becomes:
     \[
     \int e^{\sin(x)} \cos(x) \, dx = \int e^u \, du
     \]

3. **Integrate with respect to \( u \):**
   - The integral of \( e^u \) with respect to \( u \) is \( e^u \).
   - So, we get:
     \[
     e^u + C
     \]

4. **Substitute back \( u = \sin(x) \):**
   - The final answer is:
     \[
     e^{\sin(x)} + C
     \]

### Final Answer:
\[
\int \cos(x) e^{\sin(x)} \, dx = e^{\sin(x)} + C
\]
