Derivatives of Inverse Trigonometric Functions

The video tutorial explains how to find derivatives of functions involving inverse trigonometric functions. It covers derivative formulas with and without the chain rule. The first example demonstrates finding the derivative of f(x) = -2 arccot(x) without using the chain rule. The second example involves using the chain rule to find the derivative of g(x) = 5 arctan(2^x). The tutorial emphasizes understanding when to apply the chain rule and how it affects the derivative calculation.
