# How do you differentiate #f(x)=ln(6 sin^2(x^3 + 2x))# using the chain rule?

The first issue is the natural logarithm. We can use the chain rule to apply specifically to natural logarithm functions:

Applying this to the function at hand, we see that

We can simplify this very slightly to avoid length issues:

Be careful about the next step. You may be tempted to immediately try to deal with the sine function, but the overriding issue here is the fact that the sine function is squared. Use the chain rule in the case of a squared function:

This yields

We can take a moment to simplify:

Now, we can differentiate the sine function through the chain rule:

Applying this allows us to obtain

To differentiate (f(x) = \ln(6\sin^2(x^3 + 2x))) using the chain rule, follow these steps:

- Identify the inner function: (u = 6\sin^2(x^3 + 2x)).
- Differentiate the inner function: (u' = 12\sin(x^3 + 2x)\cos(x^3 + 2x)(3x^2 + 2)).
- Apply the chain rule: (f'(x) = \frac{1}{u} \cdot u').

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.
