This course will be presented through the use of cooperative and interactive learning. Critical thinking and open-ended questions and explorations will be used when appropriate. Problem solving will be emphasized throughout the course. This is a one semester course covering such standard topics as: trigonometric functions and identities, inverse trigonometric functions, graphs, solving triangles and equations, complex numbers and polar coordinates. Students will study the definitions of the trigonometric functions. Relationships between trigonometric functions will be studied as identities are established. The identities are particularly needed by students going on to a course in calculus. Graphs will give a geometric representation for both trigonometric and inverse trigonometric functions.
