To find (\frac{dy}{dx}) using implicit differentiation for the equation (\sqrt{x}+\sqrt{y}=1), differentiate both sides of the equation with respect to (x), treating (y) as a function of (x). Then, solve for (\frac{dy}{dx}). Applying implicit differentiation, the derivative of (\sqrt{x}) is (\frac{1}{2\sqrt{x}}) and the derivative of (\sqrt{y}) is (\frac{1}{2\sqrt{y}}). Thus, (\frac{d}{dx}(\sqrt{x}+\sqrt{y})=\frac{1}{2\sqrt{x}}+\frac{1}{2\sqrt{y}}). Therefore, (\frac{dy}{dx}=-\frac{\sqrt{x}}{\sqrt{y}}).

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.
