**Integration Problems**

4. Use the appropriate method of integration (rules, substitution, parts, or partial fractions) to evaluate the integral.

a. \( \int (x^2 + 6x^2) \, dx \)

b. \( \int e^{3x} \sec^2 x \, dx \)

c. \( \int \frac{2x + 6}{x^2 - 3x} \, dx \)

d. \( \int x^3 \cos x \, dx \)

e. \( \int x \ln x \, dx \)

f. \( \int \cos 4x \sin x \, dx \)

g. \( \int \frac{x^2}{x^3 - 5} \, dx \)

**Notes and Solutions:**

- The calculus problems involve finding the antiderivatives of various functions, applying techniques like substitution or integration by parts where necessary.

- The handwritten notes next to some of the problems show attempts at finding the integrals, with standard integration notation and constants of integration \( + C \) indicated.

- Some expressions may involve trigonometric or logarithmic functions, along with polynomial expressions that may require algebraic manipulation before integration.

**For Further Understanding:**

- Review techniques such as integration by substitution, integration by parts, and handling integrals involving trigonometric identities.

- Practice similar problems to build fluency in selecting and applying the right method for different types of integrals.
