Understanding the Derivative of a Function with a Non-Standard Upper Bound

The video tutorial explores the function F(x) defined as a definite integral with an upper bound of sin(x). It reviews the fundamental theorem of calculus using a simpler function h(x) and then applies the chain rule to find the derivative F'(x). The process involves defining g(x) as sin(x) and expressing F(x) in terms of h(g(x)). The tutorial concludes by calculating the derivatives and simplifying the expression, highlighting the use of the chain rule and the derivative of sine.
