    a) Use the Intermediate Value Theorem (IVT) (Theorem 9, p.84) to show that 3<?50<4.

    b) What is wrong with the following application of the Intermediate Value Theorem:
    if g:[0,?]?R and g(x)=sec?x, then since g(0)=1 and g(?)=-1, there exists a c?[0,?] such that g(c)=0?


    need help in answering this example!!

    please show step by step

    I can't tell you about part a) because of the question mark, but for b, what are the conditions to use the IVT?
