To differentiate ( f(x) = \frac{1}{\sqrt{\arctan(e^{x-1})}} ) using the chain rule, we first identify the outer function ( g(x) = \sqrt{x} ) and the inner function ( h(x) = \arctan(e^{x-1}) ). Then we differentiate the outer function with respect to the inner function, followed by differentiating the inner function with respect to ( x ). The derivative is:

[ f'(x) = -\frac{1}{2(\arctan(e^{x-1}))^{3/2}} \cdot \frac{1}{1 + (e^{x-1})^2} \cdot e^{x-1} ]

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.
