Study Guide Overview
This study guide covers the derivatives of inverse trigonometric functions. It explains the inverse function theorem and how it's used to find the derivatives of arcsin(x), arccos(x), and arctan(x). It summarizes the derivatives of all six inverse trig functions and provides a worked example and practice problems. Key terms like the chain rule and trigonometric identities are also explained.

#Introduction
In this section, we will explore the differentiation of inverse trigonometric functions. These functions are crucial in calculus and can be differentiated using various methods, including the inverse function theorem, the chain rule, and trigonometric identities.
#Inverse Function Theorem
The inverse function theorem is essential for differentiating inverse trigonometric functions. It can be written as:
or
where .
Inverse trigonometric functions are sometimes referred to using "arc" notation, e.g., is the same as .
#Differentiating Inverse Sine
To differentiate , we use the inverse function theorem:
- Let and $ f(x) = \sin ...
