We reviewed trig functions for Quadrants I and II of the unit circle in the Cartesian Plane, concentrating on 'special' right triangles (30-60-90 degree and 45-45-90 degree triangles.)

Lesson Comments
Sophia's attitude is great. She's handling the material very well.
Using radians, we explored special right triangles in Quadrants I and II. We examined the issue of representative angles and compared their trig functions with the angle between the x-axis and the radii of the unit circle.

Lesson Comments
Sophia's attitude is fine and she grasps the material well. This morning, she was a bit distracted as the result of some domestic issue that left her sleep-deprived. We got through the material well.
We reviewed the use of radians to describe the size of angles. We then used the whiteboard to discuss the unit circle centered at the origin of the Cartesian (xy) Plane.

Lesson Comments
Sophia's attitude is fine although she did whine a little about using radians rather than degrees for angular measure. She definitely "gets it."
