# need help on a univesity question Watch

1. 7.
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!!

2. I liked the bit about the question marks

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

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