Evaluate functions using cofunction and trig identities

The video tutorial covers the concepts of cosecant and secant functions, reviewing the unit circle and sine function. It explains how to handle points not on the unit circle by creating triangles and determining trigonometric functions. The tutorial also explores cofunction identities, demonstrating their relationships and applications.
