This has 2 worksheets with 15 problems each for students to determine the exact values of the 6 trigonometric functions.
They can be used in Precalculus or Trigonometry or in Calculus as a review and/or preparation for the AP Calc test.
One of the worksheets has only radians. It is the one I use as a review in Calculus on the first day.
All answers are given.
