Math 109 Section 4

Math 109, Section 1

Instructor: Joseph Hundley

Math Tutoring Is available most evenings in the open area on the second floor of the Neckers building. It's free, but you have to share the tutor(s) with whoever else is there. Information about the help sessions and open computer labs here. If you wish to hire a tutor for one-on-one sessions, the Mathematics Department office on the 3rd floor of the Neckers building maintains a list with contact info for available tutors. (Let me mention that the second floor of the Neckers building looks like the first floor from most angles, while the third floor looks like the second, and the first looks like a basement!)

My Office Is 255 on the second floor of the Neckers building. Office hours not set in stone, but I'm looking at 1:05-2:45, MWF, and Th 2-3.

Homework: Posted by 5pm each day we have class at the MathXL Portal

Curved Midterm 2 and overall grades.

Two things you can do to pick those numbers up a bit

If you've missed some homeworks, you can make them up until 10/31.
If you have less than 60 on the second midterm, you can bring that up to a 60 if you do the following:
Go to each problem you missed. Look up how to do it and write out a careful, step-by-step solution.
Make up another problem of the same type. Use your method on that problem as well.
If you get both problems right (the original and your ownt new problem), I'll add half of the original point value to your score. (Capped at 60).

Halloween Homework

Today we have a piece of "regular" homework. Get some polar graph paper (there's a link on the main course website) and draw graphs of

r = 4 cos 2 theta,
r = 1- 2 sin theta,
r = 1/(1+cos theta).

(Just plot points, then put a curve through them...)

Miscellany

Polar Graph Paper (If this site doesn't work for you, just put "Polar Graph Paper" into a search engine such as Google.)

The handouts from Sept. 8:
A circle, with the 16 "special points" marked on it.
(Corrected) Table
Graph paper. Turn sideways. After you've turned it sideways, the vertical lines correspond to the special angles (0, pi/6, pi/4, ....) and the vertical lines correspond to the numbers which come up as trig functions of these special angles....

From Sept. 10:
Graphs of the six trig functions, with the horizontal lines from Monday's graph paper marked....
More graphs...

From Sept 12:
