BRIEF QUIZ ANSWERS FOR CALCULUS II STUDENTS
In this document you will find brief answers to quiz questions.
If the quiz question is a homework problem, and the answer
is in the back of the book, then the brief answer that you
will see below will be only ``See the back of the book.''
Week 1
Week 2
- See the back of the book.
- The function f(x) = 1/x is continuous at x=1.
Therefore, since lim sin(x)/x = 1 we get
lim x/sin(x) = lim f(sin(x)/x) = f(lim sin(x)/x) =
f(1) = 1.
Week 3
- The answer is YES, cosh(x) = O(e^x).
To see this, note that lim_{x goes to infinity}
cosh(x)/e^x =
lim_{x goes to infinity}
(e^x+e^{-x})/2e^x =
lim_{x goes to infinity}
(1+e^{-2x})/2 = 1/2.
- For problems 2-5, see the back of the book.
