To find the derivative of the function sin(arc cos x), you can use the chain rule. Let y = sin(arc cos x). Then differentiate y with respect to x using the chain rule:

dy/dx = (dy/du) * (du/dx)

where u = arc cos x.

Differentiating sin(u) with respect to u gives cos(u), and differentiating arc cos x with respect to x gives -1 / sqrt(1 - x^2).

Therefore,

dy/dx = cos(arc cos x) * (-1 / sqrt(1 - x^2))

Simplify cos(arc cos x) to just x:

dy/dx = x * (-1 / sqrt(1 - x^2))

So, the derivative of sin(arc cos x) with respect to x is:

dy/dx = -x / sqrt(1 - x^2)

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.
