To find the derivative of ( f(x) = \ln(x^2 + 2) ), use the chain rule. The derivative is ( f'(x) = \frac{1}{x^2 + 2} \cdot 2x ).

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.
