Materials:

IV. PROCEDURE: A. DAILY ROUTINE B. DRILL OR REVIEW

C. LESSON PROPER 1. Motivation

The students will find words that will be related or discussed later on as the lesson goes by.

|A |M |P |
|0 |y = 2 cos 0 = 2 (1) = 2 |(0, 2) |
|0 + [pic] = [pic] |y = 2 cos [pic]= 2 (0) = 0 |([pic], 0) |
|[pic] + [pic] = π |y = 2 cos π = 2 (-1) = -2 |(π, -2) |
|π
