Homework #1 | Due Friday, Aug 26, start of class.
Please send me an e-mail from an account you use
frequently. Put "Math 170" in the subject area. You may leave
the message area blank, if you wish.
WebAssign is now up and running - see details. Note : You may do this assignment either on WebAssign (details to follow) or turn in a hand written assignment. Section 1.1 (page 10) : #1, 2, 3, 5, 9, 11, 26, 28, 37, 41, 45, 46, 55, 59, 60, 71. Section 1.2 (page 19) : 5,6,7,8,11,13,14, 15, 17, 18, 27, 31, 34, 38, 42. |

Homework #2 | Due Friday, Sept. 2, start of class.
If you have not already sent me an e-mail, please do so now. Put "Math 170" in the subject; you can leave the message area blank. This assignment is to be done on WebAssign. Problems will be listed there. Not all problems that will be due are posted yet. You can expect a total of about thirty problems due on Friday. So please check back to see that all problems have been posted. Details of how to log into WebAssign can be found here If you already know how to login, you can go directly to WebAssign here. |

All problems are to be done on WebAssign, but I've listed them here in case you'd like to do them before hand. Be aware that the problems in the book are not exactly the same as those in WebAssign.

Grades for the second midterm are shown in the graphs below.

Part II to come shortly...

### More on the hyperbolic cosine and sine (posted 10/16/2011)

The animation below shows that both the circular functions (cosine and sine) and the hyperbolic cosine sine can be parameterized by the area swept out by a point as it travels along either the circle or the hyperbola.

In the above animation, assume that the point on the circle
is parameterized in terms in argument `t` by

and that the hyperbolic, also parameterized by `t` is
given by

Then both the red area and the blue area are given by 1/2 their
respective arguments `t`.

### The catenary and the hyperbolic cosine (posted 10/12/2011)

The curve traced out the by hyperbolic cosine (`cosh(x)`)
describes the shape that a chain suspended from its endpoints would
make. This shape, called a "catenary" is also used to build
free standing arches. See here
for more examples of the catenary curve.

### Falling Ladder Paradox (posted 10/11/2011)

The classic "Falling Ladder Problem" often seen in Calculus texts as an example of a related rates problem has a physical paradox associated with it. As the height of the tip of the ladder leaning against the wall goes to zero, the speed of the tip becomes infinitely fast, according to the model used in most calculus courses. What is going wrong? You can read about the ladder paradox here and here.
