To differentiate ( f(x) = \sin(3x-2) \cdot \cos(3x-2) ), you can use the product rule, which states that the derivative of a product of two functions is the derivative of the first function times the second function plus the first function times the derivative of the second function. Applying this rule:

( f'(x) = \frac{d}{dx}(\sin(3x-2)) \cdot \cos(3x-2) + \sin(3x-2) \cdot \frac{d}{dx}(\cos(3x-2)) )

Now, differentiate each part:

( \frac{d}{dx}(\sin(3x-2)) = 3 \cos(3x-2) )

( \frac{d}{dx}(\cos(3x-2)) = -3 \sin(3x-2) )

Substitute these derivatives back into the formula:

( f'(x) = 3 \cos(3x-2) \cdot \cos(3x-2) - 3 \sin(3x-2) \cdot \sin(3x-2) )

( f'(x) = 3 \cos^2(3x-2) - 3 \sin^2(3x-2) )

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
