This is a worksheet on trigonometry / trig sum and difference formulas. This is a step by step lesson plan on how to find the exact value of trig functions when given an angle not on the unit circle. Students will explore individually or in groups how to find these exact values and how they can be derived. There is also a worksheet with practice problems to shows student comprehension.
Exploring how to find the coordinates of the unit circle using the students' knowledge of the special right triangles and how to use these coordinates to solve for the six trigonometric functions. Included in the lesson is a worksheet for solving for the trig functions, co-terminal angles, complement and supplement angles, converting from radians to degrees, and manipulating the arc length formula.
