The video tutorial explains how to find the derivative of the function f(x) = 2tan(x)/x using the quotient rule. It demonstrates the calculation of the derivative at x = pi/4, simplifies the expression, and verifies the result graphically. The tutorial also covers trigonometric function values and provides both exact and approximate results.

In the quotient rule, what is the expression for the derivative of a function f(x)/g(x)?

g(x)f'(x) - f(x)g'(x) / g(x)^2

f(x)g'(x) - g(x)f'(x) / f(x)^2

f'(x)g(x) + f(x)g'(x) / g(x)^2

g(x)f'(x) + f(x)g'(x) / f(x)^2
