Angles in Standard Positions
Students identify positive and negative angles using the Unit Circle. In this pre-calculus lesson, students identify the different angles on a unit circle using the coordinate plane and the four different quadrants as a guide. They calculate the basic trigonometric functions.

Limit Examples w/ brain malfunction on first prob (Part 4)
Sal explores more complex limit problems including showing how to take the limit of an expression with a square root by using the conjugate and how to simplify trigonometric functions that are part of limit problems. Note: A mistake is made on the last step of the first problem where multiplication should have been used instead of addition, resulting in the correct answer of 3/16.

Exploring Rational Functions
Eleventh graders differentiate between rational and their properties. In this algebra lesson, 11th graders identify the asymptote as vertical or horizontal and the graph as being continuous or not. They examine the numerator and denominator of the graph to help them predict the behavior of the graph.

Understanding Fundamental Trigonometric Identities
Students are introduced to the basic trigonometric identities. Using a diagram, they discover why the parts of the unit circle as named as they are and use equations to finalize the Pythagorean trigonometric identities. They also review basic algrebra terminology that could be useful in the present.

Optimization: The Switchboard Problem
Students explore an optimization problem. In this Pre-Calculus lesson plan, students investigate a problem in which the distance between three points is minimized in order to determine the location of a switchboard. Students use Geometer’s Sketchpad to explore and generate data, and use that data to hypothesize a function to describe the problem.
