# MAT 123

## Pre-calculus

### Introduction:

This is a webpage for the course MAT123, taught in winter 2012.

We meet on Tuesday, Wednesday, Thursday, and Friday, 930-1255 in Library-4315.

. If you need help with the course, or if you wish to learn more, do not
hesitate to visit me during my office hours. In case the time does not suit
you, we can make an appointment on any other day. Just email me.

A word of Caution: The usual autumn semester MAT123
runs for 15 weeks. Whilst, in the winter session, we squeeze that into 3 weeks, and there
are no recitations. However, the autumn version has got 3 hours of lecture per week,
while we have 14 hours. This means I should, and I shall, present the same
material and at a higher pace. But it also means that you cannot afford to
lose track. If you experience trouble keeping up with the course, please
contact me immediately.

I am planning to post some suggestions for studying for the midterm and the final, check the webpage around the time.

### Book:

The textbook we use is Blitzer's Precalculus Essentials, R. Blitzer, Pearson Prentice Hall, 20**, the edition you choose does not quite matter as long as you get the right exercises.

We shall cover selected sections from chapters 1 to 5.

### Homework:

There will be two homework assignments, to be handed on the Tuesday after, at the beginning of the lecture. See below for the assignments. Late homework will not be accepted.

There will be one midterm exams, and a final exam, both held in class:

• Midterm, Wednesday, 11th
• Final, Friday, 20th
No calculators, books or notes are allowed on the exams.

Each exam will account for 40% of your grade, with the remaining 20% determined by the homeworks. Please note that there will be no make-up exams.
