Homework Equations
The limit definition of a derivative:
[f(x+h)-f(x)]/h as h approaches zero is f'(x)
The Attempt at a Solution
I'm just not understanding the wording of the question. The limit given in the question is indeed equal to g'(x) since it's set up properly and indeed sec(pi) is -1 and subtracting -1 makes it a positive 1.
