### Integration Problem Set

#### Problem Statement:
**Find:**

a. \(\int \cos^3{x} \, dx\)

b. \(\int \sin^5{x} \, dx\)

c. \(\int \sin^4{x} \cos^3{x} \, dx\)

#### Hint:
In **(b)**:  
\[ \sin^5{x} = \sin^4{x} \sin{x} = (1 - \cos^2{x})^2 \sin{x}, \text{ etc.} \]

---

The problem set requires finding the integrals of the given trigonometric functions. The hint provided for problem (b) suggests expressing \(\sin^5{x}\) in terms of \(\cos{x}\) to facilitate the integration process. This technique might also be useful for problem (c).

For more assistance, consider the following strategies:

- **Trigonometric identities**: Use identities to simplify the integrand.
- **Substitution methods**: Particularly useful for trigonometric functions, e.g., using \(u = \sin{x}\) or \(u = \cos{x}\).

To proceed, break down each step methodically, and consider these hints and strategies to find the solutions. Happy integrating!
