Algebra II: Trigonometric Patterns

by Texas Instruments - Bell Ringer Lesson


Students use the unit circle to examine patterns in the six trigonometric functions.

Key Steps

  • Image

    Students are given the definitions of sine, cosine, and tangent and how they relate to the unit circle. Then, students are asked to use the unit circle to find the values of the functions at various angle measures to find patterns for each function.

  • Image

    Students will also explore secant, cosecant, and cotangent by finding the reciprocals of the earlier values.
