To find the derivative of ( f(x) = \ln(1 - \sin(x)) ), you can use the chain rule. The derivative of ( \ln(u) ) with respect to ( u ) is ( \frac{1}{u} ), and the derivative of ( u ) with respect to ( x ) is ( \frac{du}{dx} ). So, applying the chain rule, the derivative of ( \ln(1 - \sin(x)) ) with respect to ( x ) is ( \frac{1}{1 - \sin(x)} ) times the derivative of ( 1 - \sin(x) ) with respect to ( x ).

The derivative of ( 1 - \sin(x) ) with respect to ( x ) is ( -\cos(x) ). So, the derivative of ( f(x) = \ln(1 - \sin(x)) ) with respect to ( x ) is ( \frac{-\cos(x)}{1 - \sin(x)} ).

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.
