Find $$$\frac{d}{dx} \left(\operatorname{acos}{\left(x \right)}\right)$$$.
Solution
The derivative of the inverse cosine is $$$\frac{d}{dx} \left(\operatorname{acos}{\left(x \right)}\right) = - \frac{1}{\sqrt{1 - x^{2}}}$$$:
$${\color{red}\left(\frac{d}{dx} \left(\operatorname{acos}{\left(x \right)}\right)\right)} = {\color{red}\left(- \frac{1}{\sqrt{1 - x^{2}}}\right)}$$Thus, $$$\frac{d}{dx} \left(\operatorname{acos}{\left(x \right)}\right) = - \frac{1}{\sqrt{1 - x^{2}}}$$$.
Answer
$$$\frac{d}{dx} \left(\operatorname{acos}{\left(x \right)}\right) = - \frac{1}{\sqrt{1 - x^{2}}}$$$A
