### Integration Problem on Trigonometric and Hyperbolic Functions

**Problem Statement:**

6. Find \(\int \sinh(4x) \sin(2x) \, dx\)

In this exercise, you are tasked with finding the integral of the product of a hyperbolic sine function and a trigonometric sine function with different arguments. This problem requires knowledge of integration techniques, including integration by parts and possibly using identities related to hyperbolic and trigonometric functions.

**Explanation:**

- \(\sinh\): Hyperbolic sine function.
- \(\sin\): Trigonometric sine function.
- \(4x\): Argument of the hyperbolic sine function.
- \(2x\): Argument of the trigonometric sine function.
- \(dx\): Differential indicating integration with respect to \(x\).

To solve, you might consider applying integration by parts or using specific integrals involving products of hyperbolic and trigonometric functions. Analyzing the symmetry and properties of the involved functions can also help simplify the calculations.

This is a typical problem that combines concepts from calculus including hyperbolic functions, trigonometric functions, and techniques of integration, enhancing the problem-solving skills necessary for higher-level mathematics.
