    1. The problem statement, all variables and given/known data

    2. Relevant equations

    The limit definition of a derivative:

    [f(x+h)-f(x)]/h as h approaches zero is f'(x)

    3. 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.

    You mean ##g'(\pi)##

    So I guess you would mark it True.
