To find the maximum and minimum values of the expression

$16 \times \left(\sin^2(6x) - \sin^2(2x)\right) \times \cos(4x) - 1$

we'll analyze each component. Here’s a breakdown of the approach:

1. Simplify the expression if possible.
2. Analyze the trigonometric functions for their maximum and minimum values.
3. Determine critical points by finding the derivative and setting it to zero, if necessary.

Step-by-Step Solution

The expression includes: $\sin^2(6x) - \sin^2(2x)$ which can be rewritten using the trigonometric identity: $\sin^2(A) - \sin^2(B) = (\sin(A) + \sin(B))(\sin(A) - \sin(B))$

Thus, $\sin^2(6x) - \sin^2(2x) = (\sin(6x) + \sin(2x))(\sin(6x) - \sin(2x))$

However, since finding exact maxima and minima values may require numerical methods, I'll approximate the values by analyzing the bounds of each trigonometric part:

• Range of $\sin$ and $\cos$ functions is between $-1$ and $1$.
• Therefore, the product terms will also lie within specific bounds, influenced by $16$ and $-1$.
