***Special Announcement:
For students considering Math 111, you'll need to qualify via the Compass Test. You MUST have solid basic algebra skills to succeed in this test. The test questions build on themselves based on your comprehension of the subject matter. Basically: If you don't understand the easy stuff (Algebra 1, Geometry), they're not even going to let you try to do the hard stuff (Algebra 2, Pre-Calculus).
Here are some Extra Problems to sharpen your skills.

Summary: Day 2 involving left and rights shifts, especially when other graphing characteristics are incorporated.
Nov 4, 2011
Friday, November 4
Summary: Introduces the idea of left and right shifts when Frequency doesn't equal one, and simultaneously applies amplitude, flip, center line, frequency, and horizontal shift.
Nov 3, 2011
Thursday, November 3
Summary: Fleshing out the concept of shifting horizontally and how that looks in sine vs. cosine, as well as simultaneously combining frequency, period, amplitude, and center line.
Nov 2, 2011
Wednesday, November 2
Summary: Now that all of the characteristics of graphing have been installed, a further analysis of frequency and what happens when it changes. Also introduces the idea of a horizontal shift. Main Issue: Sine and Cosine need angles to operate, but many things that repeat themselves have nothing to do with angles.
