Greetings dear friends. In this article, we will share with you what is the derivative of arccos(x).

Derivative of arccos(x)=$-\frac{1}{\sqrt{1-x^2}}$

ðŸ‘‰ $arccos(x)=cos^{-1}x$

ðŸ‘‰ $\frac{d}{dx}arccos(x)=-\frac{1}{\sqrt{1-x^2}}$

ðŸ‘‰ $\frac{d}{dx}cos^{-1}x=-\frac{1}{\sqrt{1-x^2}}$

**Answer :**$-\frac{1}{\sqrt{1-x^2}}$
