# Chapter 3 | Techniques of Integration

## 3.7 Exercises

Evaluate the following integrals. If the integral is not convergent, answer "divergent."

**347.** \[
\int_{a}^{4} \frac{dx}{(x - 3)^2}
\]

**348.** \[
\int_{0}^{\infty} \frac{1}{4 + x^2} \, dx
\]

**349.** \[
\int_{0}^{2} \frac{1}{\sqrt{4 - x^2}} \, dx
\]

**350.** \[
\int_{0}^{1} \frac{1}{x \ln x} \, dx
\]

### Diagram Explanation:

There is a hand-drawn sketch near exercise 347. This sketch appears to be a rough graph of the function \(\frac{1}{(x-3)^2}\) along with a shaded region between \(x = 2\) and \(x = 4\), suggesting the area that is represented by the definite integral in exercise 347. A note indicating interval \([a,4]\) is also present, which is relevant to the limits of the integral.
