"If I feel unhappy, I do mathematics to become happy. If I am happy, I do mathematics to keep happy." -- (Alfred Renyi)

Math History Tidbit:

Many of the words we use to describe branches of mathematics are of Greek origin:

Arithmetic: From arithmetike, meaning "the art of counting."

Geometry: From geometrein, meaning "to measure the land."

Mathematics: From the combination of two words; one is manthanein, meaning "to learn." The other is mathema, meaning "science."

Herkimer's Corner

Why did Herkimer look for an ax on December 22?

Answer: Because there were only three chopping days left before Christmas.

Things Herky would like to know:

Why are the places called apartments when they are all stuck together?

Why do people press harder on the remote-control when they know the battery is dead?


This is due at the first class after the test on Chapter 3.

Reading: Section 4.1, pages 176 - 188.

Exercises: 4.1 and 4.2, beginning on page 188. Come to class with the data entered into your TI-83. Put the 4.1 data in lists L1 and L2. Put the 4.2 data in L3 and L4. (You do not have to address the questions asked. Just do the reading carefully and put the data into your calculator.)

Items for reflection:

You are in Section 4.1

Ok, we're thinking on a sophisticated level here.If you know basic algebra, this should make sense to you.

y =abx==> log y =log a + xlog b.The set {(x,y)} is an exponential function. The set {(x, log y)} is alinear function.

y = axb ==> log y = log a + blog x. The set {(x,y)} is a power function. The set {(log x,log y)} is a linear function.
