Differentiation of Trigonometric Functions

The video tutorial explains how to determine the derivative of functions using the product rule. It starts with deriving f(x) = cosecant x times cotangent x, applying the product rule, and simplifying the result. The tutorial then moves on to g(x) = -3 cosecant x tangent x, deriving and simplifying g'(x). The video concludes with factoring techniques and helpful tips for understanding derivatives.
