# Differentiating inverse trig functions review

Review the derivatives of the inverse trigonometric functions: arcsin(x), arccos(x), and arctan(x).

## What are the derivatives of the inverse trigonometric functions?

$\dfrac{d}{dx}\arcsin(x)=\dfrac{1}{\sqrt{1-x^2}}$
$\dfrac{d}{dx}\arccos(x)=-\dfrac{1}{\sqrt{1-x^2}}$
$\dfrac{d}{dx}\arctan(x)=\dfrac{1}{1+x^2}$
